UL(1)                     BSD General Commands Manual                    UL(1)

 

NAME


     ul - do underlining

 

SYNOPSIS


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

 

DESCRIPTION






     The ul utility reads the named files (or 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 envi-
     ronment variable TERM.  The ncurses(3) library is used 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(1).  If the terminal cannot underline, underlining is
     ignored.

     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
             underlining which is present in an nroff output stream on a crt-
             terminal.

     -t terminal
             Overrides the terminal type specified in the environment with
             terminal.

 

ENVIRONMENT


     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 environ(7)).

BUGS


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