ul(1)                                                       ul(1)



     NAME
          ul - do underlining

     SYNOPSIS
          ul [-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.  If -t is present,
          terminal is used as the terminal kind.  Otherwise, first the
          environment is searched, and if necessary, /usr/lib/terminfo
          is read to determine the appropriate sequences for
          underlining.  If none of the fields us, ue, or uc are
          present, and if so and se are present, standout mode is used
          to indicate underlining.  If the terminal can overstrike, or
          handles underlining automatically, ul behaves like cat(1).
          If the terminal cannot underline, underlining is ignored.

     EXAMPLE
               ul file1

          displays file1 on the terminal with underlined portions of
          the file either underlined, or in reverse video when this
          flag option is supported for the terminal.

     FILES
          /usr/bin/ul
          /bin/cat
               concatenate and print

          /usr/lib/terminfo

     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.
