DESCRIPTION

lates occurrences of underscores to the sequence which indicates under‐
lining for the terminal in use, as specified by the environment vari‐
able The option overrides the terminal type specified in the environ‐
ment. The terminfo(4) file corresponding to is read to determine the
appropriate sequences for underlining. If the terminal is incapable of
underlining, but is capable of a standout mode, the standout mode is
used instead. If the terminal can overstrike, or handles underlining
automatically, degenerates to If the terminal cannot underline, under‐
lining is ignored.

taining appropriate dashes this is useful when you want to look at the
underlining present in an output stream on a CRT terminal.
