About col
Reverse line-feeds filter.
Syntax
col [-b] [-f] [-p] [-x] [file]
| -b |
Assume that the output device in use is not
capable of backspacing. In this case, if two or more characters are to appear in the same place, only
the last one read will be output. |
| -f |
Although col accepts half-line motions in its input, it normally does not emit them on output. Instead, text that would appear between lines is moved to the next lower full-line boundary. This treatment can be suppressed by the -f (fine) option; in this case, the output from col may
contain forward half-line-feeds (ESC-9), but will still never contain either kind of reverse line motion. |
| -p |
Normally, col will ignore any escape sequences unknown to it that are found in its input; the -p option may be used to cause col to output these sequences as regular characters, subject to
overprinting from reverse line motions. The use of this option is highly discouraged unless the user is fully aware of the textual position of the escape sequences. |
| -x |
Prevent col from converting blank characters to tab characters on output wherever possible. Tab stops are considered to be at each column position n such that n modulo 8 equals 1. |
