NAME

       ul - do underlining

SYNOPSIS

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

DESCRIPTION

       ul  reads  the  named  filenames  (or the 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. ul uses the /usr/share/lib/terminfo entry 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  can-
       not underline, underlining is ignored.

OPTIONS

       -t terminal    Override	the  terminal  kind specified in the environment. If the terminal cannot underline, underlining is ignored. If the
		      terminal name is not found, no underlining is attempted.

       -i	      Indicate underlining by a separate line containing appropriate dashes `-'; this is useful when  you  want  to  look  at  the
		      underlining which is present in an nroff(1) output stream on a CRT-terminal.

RETURN VALUES

       ul returns exit code 1 if the file specified is not found.

FILES

BUGS

       nroff  usually  generates a series of backspaces and underlines intermixed with the text to indicate underlining. ul makes attempt to opti-
       mize the backward motion.

NAME

       colcrt - filter nroff output for CRT previewing

SYNOPSIS

       colcrt [options] [file ...]

DESCRIPTION

       colcrt  provides  virtual  half-line  and  reverse  line feed sequences for terminals without such capability, and on which overstriking is
       destructive.  Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output lines.

OPTIONS

       -, --no-underlining
	      Suppress all underlining.  This option is especially useful for previewing allboxed tables from tbl(1).

       -2, --half-lines
	      Causes all half-lines to be printed, effectively double spacing the output.  Normally, a minimal space output format is  used  which
	      will  suppress empty lines.  The program never suppresses two consecutive empty lines, however.  The -2 option is useful for sending
	      output to the line printer when the output contains superscripts and subscripts which would otherwise be invisible.

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

       -h, --help
	      Output help and exit.

EXAMPLES

       A typical use of colcrt would be

       tbl exum2.n | nroff -ms | colcrt - | more

SEE ALSO

       nroff(1), troff(1), col(1), more(1), ul(1)

BUGS

       Should fold underlines onto blanks even with the '-' option so that a true underline character would show.

       Can't back up more than 102 lines.

       General overstriking is lost; as a special case '|' overstruck with '-' or underline becomes '+'.

       Lines are trimmed to 132 characters.

       Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.

HISTORY

       The colcrt command appeared in 3.0BSD.
