.Sh NAME
|
||||||
|
.Nm ul
|
||||||
|
.Nd do underlining
|
||||||
|
.Sh SYNOPSIS
|
||||||
|
.Nm
|
||||||
|
.Op Fl i
|
||||||
|
.Op Fl t Ar terminal
|
||||||
|
.Op Ar name Ar ...
|
||||||
|
.Sh DESCRIPTION
|
||||||
|
.Nm
|
||||||
|
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
|
||||||
|
.Ev TERM .
|
||||||
|
The file
|
||||||
|
.Pa /usr/share/misc/terminfo
|
||||||
|
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,
|
||||||
|
.Nm
|
||||||
|
degenerates to
|
||||||
|
.Xr cat 1 .
|
||||||
|
If the terminal cannot underline, underlining is ignored.
|
||||||
|
.Pp
|
||||||
|
The following options are available:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Fl i
|
||||||
|
Underlining is indicated by a separate line containing appropriate
|
||||||
|
dashes `\-'; this is useful when you want to look at the underlining
|
||||||
|
which is present in an
|
||||||
|
.Xr nroff 1
|
||||||
|
output stream on a crt-terminal.
|
||||||
|
.It Fl t Ar terminal
|
||||||
|
Overrides the terminal type specified in the environment with
|
||||||
|
.Ar terminal .
|
||||||
|
.El
|
||||||
|
.Sh ENVIRONMENT
|
||||||
|
The following environment variable is used:
|
||||||
|
.Bl -tag -width TERM
|
||||||
|
.It Ev TERM
|
||||||
|
The
|
||||||
|
.Ev TERM
|
||||||
|
variable is used to relate a tty device
|
||||||
|
with its device capability description (see
|
||||||
|
.Xr terminfo 5 ) .
|
||||||
|
.Ev TERM
|
||||||
|
is set at login time, either by the default terminal type
|
||||||
|
specified in
|
||||||
|
.Pa /etc/ttys
|
||||||
|
or as set during the login process by the user in their
|
||||||
|
.Pa login
|
||||||
|
file (see for example
|
||||||
|
.Xr csh 1 Ns 's Ic setenv ) .
|
||||||
|
.El
|
||||||
|
.Sh SEE ALSO
|
||||||
|
.Xr colcrt 1 ,
|
||||||
|
.Xr man 1 ,
|
||||||
|
.Xr nroff 1
|
||||||
|
.Sh HISTORY
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
command appeared in
|
||||||
|
.Bx 3.0 .
|
||||||
|
.Sh BUGS
|
||||||
|
.Xr 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.
