COLCRT(1) BSD General Commands Manual COLCRT(1)NAMEcolcrt -- filter nroff output for CRT previewingSYNOPSIScolcrt [-] [-2] [file ...]DESCRIPTIONColcrt 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. Available options: - Suppress all underlining. This option is especially useful for previewing allboxed tables from tbl(1). -2 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.EXAMPLESA typical use of colcrt would be tbl exum2.n | nroff -ms | colcrt - | moreSEE ALSOnroff(1), troff(1), col(1), more(1), ul(1)BUGSShould 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.HISTORYThe colcrt command appeared in 3.0BSD. 3rd Berkeley Distribution June 30, 1993 3rd Berkeley Distribution
