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

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. AVAILABILITY
The colcrt command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils/util- linux/>. util-linux September 2011 COLCRT(1)
