+or
+.Sq Fl
+option is not specified, the program looks first for
+.Dq Pa distfile ,
+then
+.Dq Pa Distfile
+to use as the input.
+If no names are specified on the command line,
+.Nm rdist
+will update all of the files and directories listed in
+.Ar distfile  .
+Otherwise, the argument is taken to be the name of a file to be updated
+or the label of a command to execute. If label and file names conflict,
+it is assumed to be a label.
+These may be used together to update specific files
+using specific commands.
+.Pp
+Options specific to the second SYNOPSIS form:
+.Pp
+.Bl -tag -width Fl c
+.It Fl c
+Forces
+.Nm rdist
+to interpret the remaining arguments as a small
+.Ar distfile  .
+.Pp
+The equivalent distfile is as follows.
+.Pp
+.Bd -filled -offset indent -compact
+.Pq Ar name ...
+.Li ->
+.Op Ar login@
+.Ar host
+.Bd -filled -offset indent -compact
+.Li install
+.Op Ar dest ;
+.Ed
+.Ed
+.El
+.Pp
+Options common to both forms:
+.Pp
+.Bl -tag -width Ic
+.It Fl b
+Binary comparison. Perform a binary comparison and update files if they differ
+rather than comparing dates and sizes.
+.It Fl d Ar var=value
+Define
+.Ar var
+to have
+.Ar value  .
+The
+.Fl d
+option is used to define or override variable definitions in the
+.Ar distfile  .
+.Ar Value
+can be the empty string, one name, or a list of names surrounded by
+parentheses and separated by tabs and/or spaces.
+.It Fl h
+Follow symbolic links. Copy the file that the link points to rather than the
+link itself.
+.It Fl i
+Ignore unresolved links.
+.Nm Rdist
+will normally try to maintain the link structure of files being transferred
+and warn the user if all the links cannot be found.
+.It Fl m Ar host
+Limit which machines are to be updated. Multiple
+.Fl m
+arguments can be given to limit updates to a subset of the hosts listed in the
+.Ar distfile  .
+.It Fl n
+Print the commands without executing them. This option is
+useful for debugging
+.Ar distfile  .
+.It Fl q
+Quiet mode. Files that are being modified are normally
+printed on standard output. The
+.Fl q
+option suppresses this.
+.It Fl R
+Remove extraneous files. If a directory is being updated, any files that exist
+on the remote host that do not exist in the master directory are removed.
+This is useful for maintaining truly identical copies of directories.
+.It Fl v
+Verify that the files are up to date on all the hosts. Any files
+that are out of date will be displayed but no files will be changed
+nor any mail sent.
+.It Fl w
+Whole mode. The whole file name is appended to the destination directory
+name. Normally, only the last component of a name is used when renaming files.
+This will preserve the directory structure of the files being
+copied instead of flattening the directory structure. For example,
+renaming a list of files such as ( dir1/f1 dir2/f2 ) to dir3 would create
+files dir3/dir1/f1 and dir3/dir2/f2 instead of dir3/f1 and dir3/f2.
+.It Fl y
+Younger mode. Files are normally updated if their
+.Ar mtime
+and
+.Ar size
+(see
+.Xr stat  2  )
+disagree. The
+.Fl y
+option causes
+.Nm rdist
+not to update files that are younger than the master copy.
+This can be used
+to prevent newer copies on other hosts from being replaced.
+A warning message is printed for files which are newer than the master copy.
+.El
+.Pp
+.Ar Distfile
+contains a sequence of entries that specify the files
+to be copied, the destination hosts, and what operations to perform
+to do the updating. Each entry has one of the following formats.
+.Pp
+.Bd -literal -offset indent -compact
+<variable name> `=' <name list>
+[label:]<source list> `\->' <destination list> <command list>
+[label:]<source list> `::' <time_stamp file> <command list>
+.Ed
+.Pp
+The first format is used for defining variables.
+The second format is used for distributing files to other hosts.
+The third format is used for making lists of files that have been changed
+since some given date.
+The
+.Ar source list
+specifies a
+list of files and/or directories on the local host which are to be used
+as the master copy for distribution.
+The
+.Ar destination list
+is the list of hosts to which these files are to be
+copied.  Each file in the source list is added to a list of changes
+if the file is out of date on the host which is being updated (second format) or
+the file is newer than the time stamp file (third format).
+.Pp
+Labels are optional. They are used to identify a command for partial updates.
+.Pp
+Newlines, tabs, and blanks are only used as separators and are
+otherwise ignored. Comments begin with `#' and end with a newline.
+.Pp
+Variables to be expanded begin with `$' followed by one character or
+a name enclosed in curly braces (see the examples at the end).
+.Pp
+The source and destination lists have the following format:
+.Bd -literal -offset indent
+<name>
+.Ed
+or
+.Bd -literal -offset indent -compact
+`(' <zero or more names separated by white-space> `)'
+.Ed
+.Pp
+The shell meta-characters `[', `]', `{', `}', `*', and `?'
+are recognized and expanded (on the local host only) in the same way as
+.Xr csh  1  .
+They can be escaped with a backslash.
+The `~' character is also expanded in the same way as
+.Xr csh 1
+but is expanded separately on the local and destination hosts.
+When the
+.Fl w
+option is used with a file name that begins with `~', everything except the
+home directory is appended to the destination name.
+File names which do not begin with `/' or `~' use the destination user's
+home directory as the root directory for the rest of the file name.
+.Pp
+The command list consists of zero or more commands of the following
+format.
+.Bd -ragged -offset indent -compact
+.Bl -column except_patx pattern\ listx
+.It `install'	<options>	opt_dest_name `;'
+.It `notify'	<name list>	`;'
+.It `except'	<name list>	`;'
+.It `except_pat'	<pattern list>	`;'
+.It `special'	<name list>	string `;'
+.El
+.Ed
+.Pp
+The
+.Ic install
+command is used to copy out of date files and/or directories.
+Each source file is copied to each host in the destination list.
+Directories are recursively copied in the same way.
+.Ar Opt_dest_name
+is an optional parameter to rename files.
+If no
+.Ic install
+command appears in the command list or
+the destination name is not specified,
+the source file name is used.
+Directories in the path name will be created if they
+do not exist on the remote host.
+To help prevent disasters, a non-empty directory on a target host will
+never be replaced with a regular file or a symbolic link.
+However, under the `\-R' option a non-empty directory will be removed
+if the corresponding filename is completely absent on the master host.
+The
+.Ar options
+are `\-R', `\-h', `\-i', `\-v', `\-w', `\-y', and `\-b'
+and have the same semantics as
+options on the command line except they only apply to the files
+in the source list.
+The login name used on the destination host is the same as the local host
+unless the destination name is of the format ``login@host".
+.Pp
+The
+.Ic notify
+command is used to mail the list of files updated (and any errors
+that may have occurred) to the listed names.
+If no `@' appears in the name, the destination host is appended to
+the name
+(e.g., name1@host, name2@host, ...).
+.Pp
+The
+.Ic except
+command is used to update all of the files in the source list
+.Ic except
+for the files listed in
+.Ar name list  .
+This is usually used to copy everything in a directory except certain files.
+.Pp
+The
+.Ic except_pat
+command is like the
+.Ic except
+command except that
+.Ar pattern list
+is a list of regular expressions
+(see
+.Xr ed  1
+for details).
+If one of the patterns matches some string within a file name, that file will
+be ignored.
+Note that since `\e' is a quote character, it must be doubled to become
+part of the regular expression.  Variables are expanded in
+.Ar pattern list
+but not shell file pattern matching characters.  To include a `$', it
+must be escaped with `\e'.
+.Pp
+The
+.Ic special
+command is used to specify
+.Xr sh  1
+commands that are to be executed on the
+remote host after the file in
+.Ar name list
+is updated or installed.
+If the
+.Ar name list
+is omitted then the shell commands will be executed
+for every file updated or installed.  The shell variable `FILE' is set
+to the current filename before executing the commands in
+.Ar string  .
+.Ar String
+starts and ends with `"' and can cross multiple lines in
+.Ar distfile .
+Multiple commands to the shell should be separated by `;'.
+Commands are executed in the user's home directory on the host
+being updated.
+The
+.Ar special
+command can be used to rebuild private databases, etc.
+after a program has been updated.
+.Pp
+The following is a small example:
+.Bd -literal -offset indent
+HOSTS = ( matisse root@arpa )
+
+FILES = ( /bin /lib /usr/bin /usr/games
+\t/usr/include/{*.h,{stand,sys,vax*,pascal,machine}/*.h}

+.Sh HISTORY
+The
+.Nm rdist
+command appeared in
+.Bx 4.3 .
+.Sh DIAGNOSTICS
+A complaint about mismatch of rdist version numbers may really stem
+from some problem with starting your shell, e.g., you are in too many groups.
+.Sh BUGS
+Source files must reside on the local host where
+.Nm rdist
+is executed.
+.Pp
+There is no easy way to have a special command executed after all files
+in a directory have been updated.
+.Pp
+Variable expansion only works for name lists; there should be a general macro
+facility.
+.Pp
+.Nm Rdist
+aborts on files which have a negative mtime (before Jan 1, 1970).
+.Pp
+There should be a `force' option to allow replacement of non-empty directories
+by regular files or symlinks.  A means of updating file modes and owners
+of otherwise identical files is also needed.

+.SH DESCRIPTION
+.I Rdist
+is a program to maintain identical copies of files over multiple hosts. 
 It preserves the owner, group, mode, and mtime of files if possible and
 can update programs that are executing.
-.Nm Rdist
+.I Rdist
 reads commands from
-.Ar distfile
+.I distfile
 to direct the updating of files and/or directories.
-.Pp
-Options specific to the first SYNOPSIS form:
-.Pp
-.Bl -tag -width indent
-.It Fl
 If
-.Ar distfile
-is
-.Sq Fl ,
-the standard input is used.
-.It Fl f Ar distfile
-Use the specified
-.Ar distfile.
-.El
-.Pp
-If either the
-.Fl f
-or
-.Sq Fl
-option is not specified, the program looks first for
-.Dq Pa distfile ,
-then
-.Dq Pa Distfile
-to use as the input.
+.I distfile
+is `\-', the standard input is used.
+If no
+.B \-f
+option is present, the program looks first for `distfile',
+then `Distfile' to use as the input.
 If no names are specified on the command line,
-.Nm rdist
+.I rdist
 will update all of the files and directories listed in
-.Ar distfile  .
+.IR distfile .
 Otherwise, the argument is taken to be the name of a file to be updated
 or the label of a command to execute. If label and file names conflict,
 it is assumed to be a label.
 These may be used together to update specific files
 using specific commands.
-.Pp
-Options specific to the second SYNOPSIS form:
-.Pp
-.Bl -tag -width Fl c
-.It Fl c
-Forces
-.Nm rdist
+.PP
+The
+.B \-c
+option forces
+.I rdist
 to interpret the remaining arguments as a small
-.Ar distfile  .
-.Pp
+.IR distfile .
 The equivalent distfile is as follows.

+( \fIname\fP ... ) -> [\fIlogin\fP@]\fIhost\fP
+.ti +1i
+install	[\fIdest\fP] ;
+
+.fi
+.PP
+The
+.B \-Server
+option is recognized to provide partial backward compatible support
+for older versions of
+.I rdist
+which used this option to put
+.I rdist
+into server mode.
+If
+.I rdist
+is started with the 
+.B \-Server
+command line option, it will attempt to exec (run) the old version of
+.I rdist.
+This option will only work if 
+.I rdist
+was compiled with the location of the old rdist
+(usually either
+.I /usr/ucb/oldrdist
+or
+.I /usr/old/rdist)
+and that program is available at run time.
+.PP
+.I Rdist
+can use either the
+.I rcmd(3)
+function call or the 
+.I rsh(1c),
+remote shell, command to access each target host.
+The method used is selected at compile-time.
+If the
+.I rsh(1c)
+method is used and
+the target host is the string
+.B localhost
+and 
+the remote user name is the same as the local user name,
+.I rdist
+will run the command
+.nf
+.sp
+.RS
+.B "/bin/sh -c rdistd -S"
+.RE
+.sp
+.fi
+Otherwise
+.I rdist
+run will run the command
+.nf
+.sp
+.RS
+\fBrsh \fIhost\fB -l \fIremuser \fBrdistd -S\fR
+.RE
+.sp
+.fi
+where 
+.I host
+is the name of the target host,
+.I remuser
+is the name of the user to make the connection as and,
+.I rdistd
+is the rdist server command on the target host as shown below.
+.PP
+If the
+.I rcmd(3) 
+method is used, then
+.I rdist
+makes the connection to the target host itself and runs
+the 
+.I rdistd
+server program as shown below.
+The default, and preferred method, is to use
+.I rsh(1c)
+to make the connection to target hosts.  This allows 
+.I rdist
+to be run without being setuid to ``root''.
+.PP
+On each target host
+.I Rdist
+will attempt to run the command
+.nf
+.sp
+.RS
+.I "rdistd -S"
+.RE
+.sp
+.fi
+or
+.nf
+.sp
+.RS
+.I "<rdistd path> -S"
+.RE
+.sp
+.fi
+if the
+.I \-p
+option was specified.
+If no
+.B \-p 
+option is included,
+or the
+.I <rdistd path>
+is a simple filename,
+.I rdistd
+or
+.I <rdistd path>
+must be somewhere in the 
+.B $PATH
+of the user running
+.B rdist
+on the remote (target) host.
+.SH OPTIONS
+.TP
+.B "\-A \fInum\fR"
+Set the minimum number of free files (inodes) on a filesystem that must exist
+for 
+.I rdist
+to update or install a file.
+.TP
+.B "\-a \fInum\fR"
+Set the minimum amount of free space (in bytes) on a filesystem that must exist
+for 
+.I rdist
+to update or install a file.
+.TP
+.B \-D
+Enable copious debugging messages.
+.TP
+.B "\-d \fIvar=value\fR"
 Define
-.Ar var
+.I var
 to have
-.Ar value  .
-The
-.Fl d
+.IR value .
+This
 option is used to define or override variable definitions in the
-.Ar distfile  .
-.Ar Value
+.IR distfile .
+.I Value
 can be the empty string, one name, or a list of names surrounded by
 parentheses and separated by tabs and/or spaces.
-.It Fl h
-Follow symbolic links. Copy the file that the link points to rather than the
-link itself.
-.It Fl i
-Ignore unresolved links.
-.Nm Rdist
-will normally try to maintain the link structure of files being transferred
-and warn the user if all the links cannot be found.
-.It Fl m Ar host
+.TP
+.B \-F
+Do not fork any child 
+.I rdist
+processes.
+All clients are updated sequentially.
+.TP
+.B "\-f \fIdistfile\fR"
+Set the name of the distfile to use to be
+.I distfile .
+If 
+.I distfile
+is specified as
+``\-'' (dash)
+then read from standard input (stdin).
+.TP
+.B "\-l \fIlogopts\fR"
+Set local logging options.
+See the section 
+.B "MESSAGE LOGGING"
+for details on the syntax for
+.I logopts.
+.TP
+.B "\-L \fIlogopts\fR"
+Set remote logging options.
+.I logopts
+is the same as for local logging
+except the values are passed to the remote
+server (\fIrdistd\fR).
+See the section 
+.B "MESSAGE LOGGING"
+for details on the syntax for
+.I logopts.
+.TP
+.B "\-M \fInum\fR"
+Set the maximum number of simultaneously
+running child
+.I rdist
+processes to
+.I num.
+The default is 4.
+.TP
+.B "\-m \fImachine\fR"
 Limit which machines are to be updated. Multiple
-.Fl m
+.B \-m
 arguments can be given to limit updates to a subset of the hosts listed in the
-.Ar distfile  .
-.It Fl n
+.IR distfile .
+.TP
+.B \-n
 Print the commands without executing them. This option is
 useful for debugging
-.Ar distfile  .
-.It Fl q
-Quiet mode. Files that are being modified are normally
-printed on standard output. The
-.Fl q
-option suppresses this.
-.It Fl R
-Remove extraneous files. If a directory is being updated, any files that exist
-on the remote host that do not exist in the master directory are removed.
-This is useful for maintaining truly identical copies of directories.
-.It Fl v
+.IR distfile .
+.TP
+.B "\-o\fIdistopts\fR"
+Specify the dist options to enable.
+.I distopts
+is a comma separated list of options which are listed below.
+The valid values for
+.I distopts
+are:
+.RS
+.IP \fBverify\fR
 Verify that the files are up to date on all the hosts. Any files
 that are out of date will be displayed but no files will be changed
 nor any mail sent.
-.It Fl w
+.IP \fBwhole\fR
 Whole mode. The whole file name is appended to the destination directory
-name. Normally, only the last component of a name is used when renaming files.
+name.  Normally, only the last component of a name is used when renaming files.
 This will preserve the directory structure of the files being
 copied instead of flattening the directory structure. For example,
-renaming a list of files such as ( dir1/f1 dir2/f2 ) to dir3 would create
-files dir3/dir1/f1 and dir3/dir2/f2 instead of dir3/f1 and dir3/f2.
-.It Fl y
+rdisting a list of files such as
+.I /path/dir1/f1 
+and
+.I /path/dir2/f2 
+to 
+.I /tmp/dir 
+would create
+files 
+.I /tmp/dir/path/dir1/f1 
+and 
+.I /tmp/dir/path/dir2/f2 
+instead of 
+.I /tmp/dir/dir1/f1 
+and 
+.I /tmp/dir/dir2/f2.
+.IP \fBnoexec\fR
+Automatically exclude executable files that are in 
+.I a.out(5)
+format from being checked or updated. 
+.IP \fByounger\fR
 Younger mode. Files are normally updated if their
-.Ar mtime
+.I mtime
 and
-.Ar size
+.I size
 (see
-.Xr stat  2  )
-disagree. The
-.Fl y
+.IR stat (2))
+disagree. This
 option causes
-.Nm rdist
+.I rdist
 not to update files that are younger than the master copy.
 This can be used
 to prevent newer copies on other hosts from being replaced.
 A warning message is printed for files which are newer than the master copy.
-.El
-.Pp
-.Ar Distfile
+.IP \fBcompare\fR
+Binary comparison. Perform a binary comparison and update files if they differ
+rather than comparing dates and sizes.
+.IP \fBfollow\fR
+Follow symbolic links. Copy the file that the link points to rather than the
+link itself.
+.IP \fBignlnks\fR
+Ignore unresolved links.
+.I Rdist
+will normally try to maintain the link structure of files being transferred
+and warn the user if all the links cannot be found.
+.IP \fBchknfs\fR
+Do not check or update files on target host that
+reside on NFS filesystems.
+.IP \fBchkreadonly\fR
+Enable check on target host
+to see if a file resides on a read-only filesystem.
+If a file does, then no checking or updating of the file is attempted.
+.IP \fBchksym\fR
+If the target on the remote host is a symbolic link, but is not on the

+.SH DISTFILES
+.PP
+The

 contains a sequence of entries that specify the files
 to be copied, the destination hosts, and what operations to perform
 to do the updating. Each entry has one of the following formats.
-.Pp

 The second format is used for distributing files to other hosts.
 The third format is used for making lists of files that have been changed
 since some given date.

-.Pp
+.PP
 Labels are optional. They are used to identify a command for partial updates.
-.Pp
+.PP
 Newlines, tabs, and blanks are only used as separators and are
 otherwise ignored. Comments begin with `#' and end with a newline.
-.Pp
+.PP
 Variables to be expanded begin with `$' followed by one character or
 a name enclosed in curly braces (see the examples at the end).
-.Pp

 The source and destination lists have the following format:
-.Bd -literal -offset indent
+.nf

 <name>
-.Ed
 or
-.Bd -literal -offset indent -compact
+.ti +.5i
 `(' <zero or more names separated by white-space> `)'

+These simple lists can be modified by using one level of set addition,
+subtraction, or intersection like this:
+.nf
+
+.ti +.5i
+list '-' list
+or
+.ti +.5i
+list '+' list
+or
+.ti +.5i
+list '&' list

+If additional modifications are needed (e.g., ``all servers and client
+machines except for the OSF/1 machines'') then the list will have
+to be explicitly constructed in steps using "temporary" variables.

 The shell meta-characters `[', `]', `{', `}', `*', and `?'
 are recognized and expanded (on the local host only) in the same way as
-.Xr csh  1  .
+.IR csh (1).
 They can be escaped with a backslash.
 The `~' character is also expanded in the same way as
-.Xr csh 1
+.IR csh
 but is expanded separately on the local and destination hosts.
 When the
-.Fl w
+.B \-o\fIwhole\fR
 option is used with a file name that begins with `~', everything except the
 home directory is appended to the destination name.
 File names which do not begin with `/' or `~' use the destination user's
 home directory as the root directory for the rest of the file name.

+.SH SYNOPSIS
+.B rdistd
+.B \-S
+[
+.B \-D
+]
+.PP
+.B rdistd
+.B \-V
+.SH DESCRIPTION
+.I Rdistd
+is the server program for the
+.I rdist
+command.
+It is normally run by
+.I rdist
+via
+.I rsh(1).
+.PP
+The
+.B \-S
+argument must be specified.
+The option is required so that
+.I rdistd
+is not accidentally started 
+since
+it
+normally resides somewhere in a normal user's
+.B $PATH.
+.SH OPTIONS
+.TP
+.B \-D
+Enable debugging messages.
+Messages are logged via
+.I syslog(3).
+.TP
+.B \-V
+Print version information and exit.
+.SH FILES
+.SH "SEE ALSO"
+rdist(1), rsh(1)
+.SH BUGS
