ul(1)                                                       ul(1)



     NAME
          ul - filter special underlining sequences imbedded  in  text
          for use at a display device

     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 se-
          quence which indicates underlining.  If -t is present, ter-
          minal 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 underlin-
          ing.  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.

     EXAMPLES
               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
          /usr/lib/terminfo

     BUGS
          nroff usually outputs a series of backspaces and underlines
          intermixed with the text to indicate underlining.  No at-
          tempt is made to optimize the backward motion.
