.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
.Bl -bullet
|
|
.It
|
|
A 5-line header with the page number, date, time, and
|
|
the pathname of the file.
|
|
.It
|
|
A 5-line trailer consisting of blank lines.
|
|
.El
|
|
.Pp
|
|
If standard output is associated with a terminal,
|
|
diagnostic messages are suppressed until the
|
|
.Nm
|
|
utility has completed processing.
|
|
.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.
|
|
Lines are not truncated under single column output.
|
|
.Sh OPTIONS
|
|
In the following option descriptions, column, lines, offset, page, and
|
|
width are positive decimal integers and gap is a nonnegative 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 Xo
|
|
.Op Ar char Ns
|
|
.Op Ar gap
|
|
.Xc
|
|
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 h Ar header
|
|
Use the string
|
|
.Ar header
|
|
to replace the
|
|
.Ar file name
|
|
in the header line.
|
|
.It Fl i Xo
|
|
.Op Ar char Ns
|
|
.Op Ar gap
|
|
.Xc
|
|
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 locale
|
|
Use
|
|
.Ar locale
|
|
specified as argument instead of one found in environment.
|
|
Use "C" to reset locale to default.
|
|
.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
|
|
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 Xo
|
|
.Op Ar char Ns
|
|
.Op Ar width
|
|
.Xc
|
|
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
|
|
receives an interrupt while printing to a terminal, it
|
|
flushes all accumulated error messages to the screen before
|
|
terminating.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
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).
