+.Sh NAME
+.Nm sysexits
+.Nd preferable exit codes for programs
+.Sh SYNOPSIS
+.Fd #include <sysexits.h>
+.Sh DESCRIPTION
+According to
+.Xr style 9 ,
+it is not a good practice to call
+.Xr exit 3
+with arbitrary values to indicate a failure condition when ending
+a program.  Instead, the pre-defined exit codes from
+.Nm sysexits
+should be used, so the caller of the process can get a rough
+estimation about the failure class without looking up the source code.
+.Pp
+The successful exit is always indicated by a status of 0, or
+.Sy EX_OK .
+Error numbers begin at
+.Sy EX__BASE
+to reduce the possibility of clashing with other exit statuses that
+random programs may already return.  The meaning of the codes is
+approximately as follows:
+.Bl -tag -width "EX_UNAVAILABLEXX(XX)"
+.It Sy EX_USAGE Pq 64
+The command was used incorrectly, e.g., with the wrong number of
+arguments, a bad flag, a bad syntax in a parameter, or whatever.
+.It Sy EX_DATAERR Pq 65
+The input data was incorrect in some way.  This should only be used
+for user's data and not system files.
+.It Sy EX_NOINPUT Pq 66
+An input file (not a system file) did not exist or was not readable.
+This could also include errors like
+.Dq \&No message
+to a mailer (if it cared to catch it).
+.It Sy EX_NOUSER Pq 67
+The user specified did not exist.  This might be used for mail
+addresses or remote logins.
+.It Sy EX_NOHOST Pq 68
+The host specified did not exist.  This is used in mail addresses or
+network requests.
+.It Sy EX_UNAVAILABLE Pq 69
+A service is unavailable.  This can occur if a support program or file
+does not exist.  This can also be used as a catchall message when
+something you wanted to do doesn't work, but you don't know why.
+.It Sy EX_SOFTWARE Pq 70
+An internal software error has been detected.  This should be limited
+to non-operating system related errors as possible.
+.It Sy EX_OSERR Pq 71
+An operating system error has been detected.  This is intended to be
+used for such things as
+.Dq cannot fork ,
+.Dq cannot create pipe ,
+or the like.  It includes things like getuid returning a user that
+does not exist in the passwd file.
+.It Sy EX_OSFILE Pq 72
+Some system file (e.g.,
+.Pa /etc/passwd ,
+.Pa /var/run/utmp ,
+etc.) does not exist, cannot be opened, or has some sort of error
+(e.g., syntax error).
+.It Sy EX_CANTCREAT Pq 73
+A (user specified) output file cannot be created.
+.It Sy EX_IOERR Pq 74
+An error occurred while doing I/O on some file.
+.It Sy EX_TEMPFAIL Pq 75
+Temporary failure, indicating something that is not really an error.
+In sendmail, this means that a mailer (e.g.) could not create a
+connection, and the request should be reattempted later.
+.It Sy EX_PROTOCOL Pq 76
+The remote system returned something that was
+.Dq not possible
+during a protocol exchange.
+.It Sy EX_NOPERM Pq 77
+You did not have sufficient permission to perform the operation.  This
+is not intended for file system problems, which should use
+.Sy EX_NOINPUT
+or
+.Sy EX_CANTCREAT ,
+but rather for higher level permissions.
+.It Sy EX_CONFIG Pq 78
+Something was found in an unconfigured or misconfigured state.
+.El
+.Pp
+The numerical values corresponding to the symbolical ones are given in
+parenthesis for easy reference.

+.Bx 4.3 .

+This man page has been written by

+.Pa <sysexits.h> .
+.Sh BUGS
+The choice of an appropriate exit value is often ambiguous.
