ul(1)                                                       ul(1)



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

SYNOPSIS
     ul [-t terminal] [file]...

ARGUMENTS
     file Specifies the file that is to be run through the
          filter.

     -t terminal
          Specifies the type of terminal being used.  If this
          option is not given, 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.

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 the terminal can overstrike, or handles underlining
     automatically, ul behaves like cat.  If the terminal cannot
     underline, underlining is ignored.

EXAMPLES
     Enter this command:

        ul file1

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

LIMITATIONS
     The nroff program usually outputs a series of backspaces and
     underlines intermixed with the text to indicate underlining.
     No attempt is made to optimize the backward motion.
