col—Filter reverse line feeds from input
col [-bfx] [-l num]
col filters out reverse (and half-reverse) line feeds so the output is in the correct order with only forward and half-forward line feeds, and replaces whitespace characters with tabs where possible. This can be useful in processing the output of nroff(1) and tbl(1). col reads from standard input and writes to standard output.
The options are as follows:
|-b||Do not output any backspaces, printing only the last character written to each column position.|
|-f||Forward half-line feeds are permitted (fine mode). Normally characters printed on a half-line boundary are printed on the following line.|
|-x||Output multiple spaces instead of tabs.|
|-lnum||Buffer at least num lines in memory. By default, 128 lines are buffered.|
