NAME

     ul -- do underlining

SYNOPSIS

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

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 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 terminal can overstrike, or handles underlining automatically, ul degenerates to cat(1).	If the terminal cannot underline,
     underlining is ignored.  During the translation some other special characters also get translated.  E.g. TAB gets expanded to spaces.

     The following options are available:

     -i      Underlining is indicated by a separate line containing appropriate dashes '-'; this is useful when you want to look at the underlin-
	     ing 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

     The LANG, LC_ALL, LC_CTYPE and TERM environment variables affect the execution of ul as described in environ(7).

EXIT STATUS

     The ul utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

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

HISTORY

     The ul command appeared in 3.0BSD.

BUGS

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

NAME

       ul - do underlining

SYNOPSIS

       ul [options] [file ...]

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 terminfo database is read to determine the  appro-
       priate  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  under-
       line, underlining is ignored.

OPTIONS

       -i, --indicated
	      Underlining is indicated by a separate line containing appropriate dashes `-'; this is useful when you want to look at the underlin-
	      ing which is present in an nroff output stream on a crt-terminal.

       -t, -T, --terminal terminal
	      Overrides the terminal type specified in the environment with TERM.

       -V, --version
	      Display version information and exit.

       -h, --help
	      Display a help text and exit.

ENVIRONMENT

       The following environment variable is used:

       TERM   The TERM variable is used to relate a tty device with its device capability description (see terminfo(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)).

SEE ALSO

       colcrt(1), login(1), man(1), nroff(1), setenv(1), terminfo(5)

BUGS

       Nroff usually outputs a series of backspaces and underlines intermixed with the text to indicate underlining.  No attempt is made to  opti-
       mize the backward motion.

HISTORY

       The ul command appeared in 3.0BSD.

AVAILABILITY
