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 appropriate 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 automati-
       cally, 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  opti-
       mize the backward motion.
