LAM(1) General Commands Manual LAM(1)
lam – laminate files
lam [-f min.max] [-s sepstring] [-t c] file ...
lam [-p min.max] [-s sepstring] [-t c] file ...
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.
Normally, each option affects only the file after it. If the option letter
is capitalized it affects all subsequent files until it appears again
uncapitalized. The options are described below:
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.
Like -f, but pad this file's field when end-of-file is reached and
other files are still active.
Print sepstring before printing line fragments from the next file.
This option may appear after the last file.
-t c The input line terminator is c instead of a newline. The newline
normally appended to each output line is omitted.
To print files simultaneously for easy viewing use pr(1).
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
and a form letter with substitutions keyed by `@' can be done with
lam -t @ letter changes
join(1), paste(1), pr(1), printf(3)
Some of the functionality of lam is standardized as the paste(1) utility by
IEEE Std 1003.2 (“POSIX.2”).
The lam utility does not recognize multibyte characters.
