col —
| col | [ -bfpx] [-lnum] | 
col filters out reverse (and half reverse) line feeds so
  that the output is in the correct order with only forward and half forward
  line feeds, and replaces white-space characters with tabs where possible. This
  can be useful in processing the output of
  nroff(1) and
  tbl(1).
col reads from the standard input and
    writes to the standard output.
The options are as follows:
-b-f-pcol will filter out any control sequences from the
      input other than those recognized and interpreted by itself, which are
      listed below.-x-l
    numThe control sequences for carriage motion that
    col understands and their decimal values are listed
    in the following table:
All unrecognized control characters and escape sequences are discarded.
col keeps track of the character set as
    characters are read and makes sure the character set is correct when they
    are output.
If the input attempts to back up to the last flushed line,
    col will display a warning message.
col utility conforms to X/Open
  Portability Guide Issue 4, Version 2
  (“XPG4.2”). The -l option is an
  extension to the standard.
col command appeared in
  Version 6 AT&T UNIX.
