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.  Ul also translates overstruck characters to bold,
       where appropriate.  The -t option overrides the terminal kind
       specified in the environment.  Ul uses information from the terminfo
       database to determine the appropriate sequences for underlining and
       emboldening.  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 automatically, 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.

EXAMPLES
       $ ul file01

       This command reads the file "file01" and translates occurrences of
       underscores to the sequence which indicates underlining for the
       terminal in use.  If the terminal does not support underlining, ul
       displays the file just as cat would.

BUGS
       For users of groff or Xroff: 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.
