LAM(1) FreeBSD General Commands Manual LAM(1)
NAME
lam - laminate files
SYNOPSIS
lam [-f min.max] [-s sepstring] [-t c] file ...
lam [-p min.max] [-s sepstring] [-t c] file ...
DESCRIPTION
The lam utility copies the named files side by side onto the standard
output. The n-th input lines from the input files are considered
fragments of the single long n-th output line into which they are
assembled. The name `-' means the standard input, and may be repeated.
-f min.max, -F min.max
Print line fragments according to the format string min.max,
where min is the minimum field width and max the maximum field
width. If 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. Using -f applies only to the
next file while -F applies to all subsequent files until it
appears again uncapitalized.
-p min.max, -P min.max
Like -f, but pad this file's field when end-of-file is reached
and other files are still active. Using -p applies only to the
next file while -P applies to all subsequent files until it
appears again uncapitalized.
-s sepstring, -S sepstring
Print sepstring before printing line fragments from the next
file. This option may appear after the last file. Using -s
applies only to the next file while -S applies to all subsequent
files until it appears again uncapitalized.
-t c, -T c
The input line terminator is c instead of a newline. The newline
normally appended to each output line is omitted. Using -t
applies only to the next file while -T applies to all subsequent
files until it appears again uncapitalized.
To print files simultaneously for easy viewing use pr(1).
EXAMPLES
The command
lam file1 file2 file3 file4
joins 4 files together along each line. To merge the lines from four
different files use
lam file1 -S "\
" file2 file3 file4
Every 2 lines of a file may be joined on one line with
lam - - < file
STANDARDS
Some of the functionality of lam is standardized as the paste(1) utility
by IEEE Std 1003.2 ("POSIX.2").

The lam utility first appeared in 4.2BSD.
