NAME
       ul - do underlining

SYNOPSIS
       ul [ -i ] [ -t terminal ] [ name ...  ]

DESCRIPTION
       Ul  reads  the  named  files  (or standard input if none are given) and
       translates occurrences of underscores to the sequence  which  indicates
       underlining  for  the  terminal in use, as specified by the environment
       variable TERM.  The -t option overrides the terminal kind specified  in
       the environment.  The file /etc/termcap is read to determine the appro‐
       priate sequences for underlining.  If  the  terminal  is  incapable  of
       underlining,  but  is  capable  of  a  standout  mode then that is used
       instead.  If the terminal can overstrike, or handles underlining  auto‐
       matically, ul degenerates to cat(1).  If the terminal cannot underline,
       underlining is ignored.

       The -i option causes ul to indicate underlining onto by a separate line
       containing appropriate dashes ‘-’; this is useful when you want to look
       at the underlining which is present in an nroff output stream on a crt-
       terminal.

BUGS
       Nroff  usually outputs a series of backspaces and underlines intermixed
       with the text to indicate underlining.  No attempt is made to  optimize
       the backward motion.
