NAME
     ul - do underlining

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

     The options are as follows:

     -i	     Underlining is indicated by a separate line containing
	     appropriate dashes (`-').

     -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)).
