UL(1)                        BSD Reference Manual                        UL(1)

NAME

     ul - do underlining

SYNOPSIS

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

DESCRIPTION

     ul 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 environment
     variable TERM. The file /etc/termcap is read 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 ter-
     minal can overstrike, or handles underlining automatically, ul degen-
     erates to cat(1). If the terminal cannot underline, underlining is ig-
     nored.

     The options are as follows:

     -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(1) output stream on a
             CRT-terminal.

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

ENVIRONMENT

     TERM  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)).

SEE ALSO

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

HISTORY

     The ul command appeared in 3.0BSD.

BUGS

     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.
