UL(1)                      OpenBSD Reference Manual                      UL(1)

     ul - do underlining

     ul [-i] [-t terminal] [name ...]

     ul reads the named files (or standard input if none are given) and trans-
     lates occurrences of underscores to the sequence which indicates under-
     lining for the terminal in use, as specified by the environment variable
     TERM. The file /etc/termcap is read to determine the appropriate se-
     quences 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 degen-
     erates to cat(1).  If the terminal cannot underline, underlining is ig-

     The following options are available:

     -i      Underlining is indicated by a separate line containing appropri-
             ate dashes `-'; this is useful when you want to look at the un-
             derlining which is present in an nroff(1) output stream on a crt-

     The following environment variable is used:

     TERM  The TERM variable is used to relate a tty device with its device
           capability description (see termcap(5)).  TERM is set at login
           time, either by the default terminal type specified in /etc/ttys or
           as set during the login process by the user in their login file
           (see setenv(1)).

     colcrt(1),  man(1),  nroff(1)

     nroff(1) usually outputs a series of backspaces and underlines intermixed
     with the text to indicate underlining.  No attempt is made to optimize
     the backward motion.

     The ul command appeared in 3.0BSD.
