ul(1bsd)

ul -- (BSD) underline

Synopsis

   /usr/ucb/ul [-i] [-t terminal] [file . . .]

Description

The ul command reads the named files (or the 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 uses the /usr/share/lib/termcap file 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 automatically, ul degenerates to cat. If the terminal cannot underline, underlining is ignored.

The following options are available:

-t terminal: Override the terminal kind specified in the environment. If the terminal cannot underline, underlining is ignored.
-i: Indicate underlining 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.
