.SH DESCRIPTION
|
||
|
|
.I Lam
|
||
|
|
copies the named files side by side onto the standard output.
|
||
|
|
The
|
||
|
|
.IR n -th
|
||
|
|
input lines from the input
|
||
|
|
.IR file s
|
||
|
|
are considered fragments of the single long
|
||
|
|
.IR 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
|
||
|
|
.I file
|
||
|
|
after it.
|
||
|
|
If the option letter is capitalized it affects all subsequent files
|
||
|
|
until it appears again uncapitalized.
|
||
|
|
The options are described below.
|
||
|
|
.IP \fB\-f\fP\ min.max
|
||
|
|
Print line fragments according to the format string
|
||
|
|
.IR min.max ,
|
||
|
|
where
|
||
|
|
.I min
|
||
|
|
is the minimum field width and
|
||
|
|
.I max
|
||
|
|
the maximum field width.
|
||
|
|
If
|
||
|
|
.I 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.
|
||
|
|
.IP \fB\-p\fP\ min.max
|
||
|
|
Like \fB\-f\fP,
|
||
|
|
but pad this file's field when end-of-file is reached
|
||
|
|
and other files are still active.
|
||
|
|
.IP \fB\-s\fP\ sepstring
|
||
|
|
Print
|
||
|
|
.I sepstring
|
||
|
|
before printing line fragments from the next file.
|
||
|
|
This option may appear after the last file.
|
||
|
|
.IP \fB\-t\fP\ c
|
||
|
|
The input line terminator is
|
||
|
|
.I c
|
||
|
|
instead of a newline.
|
||
|
|
The newline normally appended to each output line is omitted.
|
||
|
|
.PP
|
||
|
|
To print files simultaneously for easy viewing use
|
||
|
|
.IR pr (1).

|
|
.IC
|
||
|
|
lam file1 file2 file3 file4
|
||
|
|
.NC
|
||

|
joins 4 files together along each line.
|
||
|
|
To merge the lines from four different files use
|
||
|
|
.IC
|
||
|
|
lam file1 \-S "\\

|
||
|
|
.IC
|
||
|
|
lam \- \- < file
|
||
|
|
.NC
|
