.Sh DESCRIPTION
|
|
.Nm Lam
|
|
copies the named files side by side onto the standard output.
|
|
The
|
|
.Em n-th
|
|
input lines from the input
|
|
.Ar files
|
|
are considered fragments of the single long
|
|
.Em n-th
|
|
output line into which they are assembled.
|
|
The name `\fB\-\fP' means the standard input, and may be repeated.
|
|
.Pp
|
|
Normally, each option affects only the
|
|
.Ar file
|
|
after it.
|
|
If the option letter is capitalized it affects all subsequent files
|
|
until it appears again uncapitalized.
|
|
The options are described below.
|
|
.Bl -tag -width indent
|
|
.It Fl f Ar min . Ns Ar max
|
|
Print line fragments according to the format string
|
|
.Ar min . Ns Ar max ,
|
|
where
|
|
.Ar min
|
|
is the minimum field width and
|
|
.Ar max
|
|
the maximum field width.
|
|
If
|
|
.Ar min
|
|
begins with a zero, zeros will be added to make up the field width,
|
|
and if it begins with a `\-', the fragment will be left-adjusted
|
|
within the field.
|
|
.It Fl p Ar min . Ns Ar max
|
|
Like
|
|
.Fl f ,
|
|
but pad this file's field when end-of-file is reached
|
|
and other files are still active.
|
|
.It Fl s Ar sepstring
|
|
Print
|
|
.Ar sepstring
|
|
before printing line fragments from the next file.
|
|
This option may appear after the last file.
|
|
.It Fl t Ar c
|
|
The input line terminator is
|
|
.Ar c
|
|
instead of a newline.
|
|
The newline normally appended to each output line is omitted.
|
|
.El
|
|
.Pp
|
|
To print files simultaneously for easy viewing use
|
|
.Xr pr 1 .
|
|
.Sh EXAMPLES
|
|
The command
|
|
.Bd -literal
|
|
lam file1 file2 file3 file4
|
|
.Ed
|
|
.Pp
|
|
joins 4 files together along each line.
|
|
To merge the lines from four different files use
|
|
.Bd -literal
|
|
lam file1 \-S "\\
|
|
" file2 file3 file4
|
|
.Ed
|
|
.Pp
|
|
Every 2 lines of a file may be joined on one line with
|
|
.Bd -literal
|
|
lam \- \- < file
|
|
.Ed
|
|
.Pp
|
|
and a form letter with substitutions keyed by `@' can be done with
|
|
.Bd -literal
|
|
lam \-t @ letter changes
