POSIX.2, X/Open Portability Guide, UNIX systems.
The –b and –x options and the seek pointers are extensions of the POSIX
standard.
col — Remove reverse line feeds
Format
col [–bfpx] [file ...]
Note: The col utility is fully supported for compatibility with older UNIX systems.
However, because it is no longer supported by POSIX.2 IEEE standard
1003.2-1992, this utility should be avoided for applications intended to be
portable to other UNIX-branded systems.
