UL(1)                       General Commands Manual                      UL(1)



NAME
       ul - do underlining

SYNOPSIS
       ul [ -i ] [ -t terminal ] [ filename...  ]

DESCRIPTION
       ul  reads the named filenames (or the standard input if none are given)
       and translates occurrences of underscores to the sequence  which  indi-
       cates underlining for the terminal in use, as specified by the environ-
       ment variable TERM.  ul uses the /etc/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 auto-
       matically, ul degenerates to cat(1V).  If the  terminal  cannot  under-
       line, underlining is ignored.

OPTIONS
       -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 under-
              lining which is present in an nroff(1) output stream on  a  CRT-
              terminal.

FILES
       /etc/termcap

SEE ALSO
       cat(1V), colcrt(1), man(1), nroff(1)

BUGS
       nroff  usually  generates  a series of backspaces and underlines inter-
       mixed with the text to indicate underlining.  ul makes attempt to opti-
       mize the backward motion.
