lam

Synopsis

    lam [options] file ...

Laminate files. Lines are read from the given files and pasted together side by side. In other words, line 1 of the output is the concatenation of line 1 from each input file, line 2 is the concatenation of line 2 from each input file, and so on. Use - to mean standard input.

Options

-f min . max

Use min as the minimum field width for the following file’s lines, and max as the maximum field width. min may start with a zero, in which case padding is done with zeros. It may also start with a -, in which case the output is left-adjusted.

-F min . max

Like -f, but apply the field width specification to all following input files, until another -f is encountered.

-p min . max

Like -f, but pad this file’s field in the output if end-of-file is encountered on it while the other files still have data.

-P min . max

Like -p, but apply the field width specification to all following input files, until another -p is encountered.

-s sep

Print sep after the following file’s line, before the line from the next file. Normally, the lines are joined without any intervening separator.

-S sep

Like -S, but apply the separator specification to all following input files, until another -s is encountered.

-t char

Input lines are terminated by the character char, instead of newline.

-T char

Like -t, but apply the input line terminator specification to all following input files, until another -t is encountered.
