<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B></B>
|
|
|
|
|
|
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
|
|
<B>TERM</B>
|
|
|
|
|
|
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,
|
|
<B></B>
|
|
|
|
|
|
degenerates to
|
|
<A HREF="/cgi-bin/man/man2html?1+cat">cat</A>(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.

|

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
|
|

The

|
|
|
|
|
|
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.
