1.1 ! root 1: .TH UL 1 "18 January 1983" ! 2: .UC 4 ! 3: .SH NAME ! 4: ul \- do underlining ! 5: .SH SYNOPSIS ! 6: .B ul ! 7: [ ! 8: .B \-i ! 9: ] [ ! 10: .B \-t ! 11: .I terminal ! 12: ] ! 13: [ ! 14: .I name ! 15: \&... ! 16: ] ! 17: .SH DESCRIPTION ! 18: .I Ul ! 19: reads the named files (or standard input if none are given) ! 20: and translates occurrences of underscores to the sequence ! 21: which indicates underlining for the terminal in use, as specified ! 22: by the environment variable ! 23: TERM. ! 24: The ! 25: .B \-t ! 26: option overrides the terminal kind specified in the environment. ! 27: The file ! 28: .I /etc/termcap ! 29: is read to determine the appropriate sequences for underlining. ! 30: If the terminal is incapable of underlining, but is capable of ! 31: a standout mode then that is used instead. ! 32: If the terminal can overstrike, ! 33: or handles underlining automatically, ! 34: .I ul ! 35: degenerates to ! 36: .IR cat (1). ! 37: If the terminal cannot underline, underlining is ignored. ! 38: .PP ! 39: The ! 40: .B \-i ! 41: option causes ! 42: .I ul ! 43: to indicate underlining onto by a separate line containing appropriate ! 44: dashes `\-'; this is useful when you want to look at the underlining ! 45: which is present in an ! 46: .I nroff ! 47: output stream on a crt-terminal. ! 48: .SH "SEE ALSO" ! 49: man(1), nroff(1), colcrt(1) ! 50: .SH AUTHOR ! 51: Mark Horton wrote ! 52: .IR ul . ! 53: The ! 54: .B \-i ! 55: option was originally a option of the editor ! 56: .IR ex (1), ! 57: then an ! 58: .I iul ! 59: command. ! 60: .SH BUGS ! 61: .I Nroff ! 62: usually outputs a series of backspaces and underlines intermixed ! 63: with the text to indicate underlining. No attempt is made to optimize ! 64: the backward motion.
