.Sh DESCRIPTION
The
.Nm pr
utility is a printing and pagination filter for text files.
When multiple input files are specified, each is read, formatted,
and written to standard output.
By default, the input is separated into 66-line pages, each with
.sp
.in +2
.ti -2
\(bu A 5-line header with the page number, date, time, and
the pathname of the file.
.sp
.ti -2
\(bu A 5-line trailer consisting of blank lines.
.in -2
.Pp
Optionally, the trailer can be replaced by a
.Em <form-feed>
where this is more appropriate for the output device being used and
.Em <tab>s
can be expanded to input relative
.Em <spaces>s
or
.Em <space>s
can contracted to output relative
.Em <tab>s .
The
.Nm pr
utility also interprets
.Em <form-feed>s
in the input as logical end of pages.
.Pp
When multiple column output is specified,
text columns are of equal width.
By default text columns are separated by at least one
.Em <blank> .
Input lines that do not fit into a text column are truncated, except
in the default single columns output mode.
.Pp
If standard output is associated with a terminal,
diagnostic messages are suppressed until the
.Nm pr
utility has completed processing.
.Sh OPTIONS
In the following option descriptions,
.Em column ,
.Em lines ,
.Em offset ,
.Em page ,
and
.Em width
are positive decimal integers and
.Em gap
is a non-negative decimal integer.
.Bl -tag -width 4n
.It Ar \&+page
Begin output at page number
.Ar page
of the formatted input.
.It Fl Ar column
Produce output that is
.Ar columns
wide (default is 1) that is written vertically
down each column in the order in which the text
is received from the input file.
The options
.Fl e
and
.Fl i
are assumed.
This option should not be used with
.Fl m .
When used with
.Fl t ,
the minimum number of lines is used to display the output.
.It Fl a
Modify the effect of the
.Fl column
option so that the columns are filled across the page in a round-robin order
(e.g., when column is 2, the first input line heads column
1, the second heads column 2, the third is the second line
in column 1, etc.).
This option requires the use of the
.Fl column
option.
.It Fl d
Produce output that is double spaced. An extra
.Em <newline>
character is output following every
.Em <newline>
found in the input.
.It Fl e Ar \&[char\&]\&[gap\&]
Expand each input
.Em <tab>
to the next greater column
position specified by the formula
.Ar n*gap+1 ,
where
.Em n
is an integer > 0.
If
.Ar gap
is zero or is omitted the default is 8.
All
.Em <tab>
characters in the input are expanded into the appropriate
number of
.Em <space>s .
If any nondigit character,
.Ar char ,
is specified, it is used as the input tab character.
.It Fl F
Use a
.Em <form-feed>
character for new pages,
instead of the default behavior that uses a
sequence of
.Em <newline>
characters.
.It Fl f
Same as the
.Fl F
option.
.It Fl h Ar header
Use the string
.Ar header
to replace the
.Ar file name
in the header line.
.It Fl i Ar \&[char\&]\&[gap\&]
In output, replace multiple
.Em <space>s
with
.Em <tab>s
whenever two or more
adjacent
.Em <space>s
reach column positions
.Ar gap+1 ,
.Ar 2*gap+1 ,
etc.
If
.Ar gap
is zero or omitted, default
.Em <tab>
settings at every eighth column position
is used.
If any nondigit character,
.Ar char ,
is specified, it is used as the output
.Em <tab>
character.
.It Fl l Ar lines
Override the 66 line default and reset the page length to
.Ar lines .
If
.Ar lines
is not greater than the sum of both the header and trailer
depths (in lines), the
.Nm pr
utility suppresses output of both the header and trailer, as if the
.Fl t
option were in effect.
.It Fl m
Merge the contents of multiple files.
One line from each file specified by a file operand is
written side by side into text columns of equal fixed widths, in
terms of the number of column positions.
The number of text columns depends on the number of
file operands successfully opened.
The maximum number of files merged depends on page width and the
per process open file limit.
The options
.Fl e
and
.Fl i
are assumed.
.It Fl n Ar \&[char\&]\&[width\&]
Provide
.Ar width
digit line numbering.
The default for
.Ar width ,
if not specified, is 5.
The number occupies the first
.Ar width
column positions of each text column or each line of
.Fl m
output.
If
.Ar char
(any nondigit character) is given, it is appended to the line number to
separate it from whatever follows. The default for
.Ar char
is a
.Em <tab> .
Line numbers longer than
.Ar width
columns are truncated.
.It Fl o Ar offset
Each line of output is preceded by
.Ar offset
.Em <spaces>s .
If the
.Fl o
option is not specified, the default is zero.
The space taken is in addition to the output line width.
.It Fl r
Write no diagnostic reports on failure to open a file.
.It Fl s Ar char
Separate text columns by the single character
.Ar char
instead of by the appropriate number of
.Em <space>s
(default for
.Ar char
is the
.Em <tab>
character).
.It Fl t
Print neither the five-line identifying
header nor the five-line trailer usually supplied for each page.
Quit printing after the last line of each file without spacing to the
end of the page.
.It Fl w Ar width
Set the width of the line to
.Ar width
column positions for multiple text-column output only.
If the
.Fl w
option is not specified and the
.Fl s
option is not specified, the default width is 72.
If the
.Fl w
option is not specified and the
.Fl s
option is specified, the default width is 512.
.It Ar file
A pathname of a file to be printed.
If no
.Ar file
operands are specified, or if a
.Ar file
operand is
.Sq Fl ,
the standard input is used.
The standard input is used only if no
.Ar file
operands are specified, or if a
.Ar file
operand is
.Sq Fl .
.El
.Pp
The
.Fl s
option does not allow the option letter to be separated from its
argument, and the options
.Fl e ,
.Fl i ,
and
.Fl n
require that both arguments, if present, not be separated from the option
letter.
.Sh ERRORS
If
.Nm pr
receives an interrupt while printing to a terminal, it
flushes all accumulated error messages to the screen before
terminating.
.Pp
The
.Nm pr
utility exits 0 on success, and 1 if an error occurs.
.Pp
Error messages are written to standard error during the printing
process (if output is redirected) or after all successful
file printing is complete (when printing to a terminal).
.Sh NOTES
The interpretation of
.Em <form-feed>s
in the input stream is that they are special
.Em <newline>s
which have the side effect of causing a page break.  While this works
correctly for all cases, strict interpretataion also implies that the
common convention of placing a
.Em <form-feed>
on a line by itself is actually interpreted as a blank line, page break,
blank line.
.Sh RESTRICTIONS
The
.Nm pr
utility is intended to paginate input containing basic
.Xr ascii 7
text formatting and input streams containing non-printing
.Em <control-characters> ,
.Em <escape-sequences>
or long lines may result in formatting errors.
.Pp
The
.Nm pr
utility does not currently understand over-printing using
.Em <back-space>
or
.Em <return>
characters, and except in the case of unmodified single-column output,
use of these characters will cause formatting errors.
.Sh BUGS
The lack of a line wrapping option, and the specification that truncation
does not apply to single-column output frequently results in formatting
errors when input lines are longer than actual line width of the output device.
.Pp
The default width of 72 is archaic and non-obvious since it is normally
ignored in the default single column mode.  Using the
.Fl m
option with one column provides a way to truncate single column output but
there's no way to wrap long times to a fixed line width.
.Pp
The default of
.Em <tab>
for the separator for the
.Fl n
and
.Fl s
options often results in lines apparently wider than expected.

.Xr more 1 ,

.Sh STANDARDS
The
.Nm pr
utility is
.St -p1003.2
compatible; however, that standard is relatively silent concerning the
handling of input characters beyond the behavior dictated by the
.Nm pr
required command
options.
