Annotation of os2sdk/demos/apps/cpgrep/cpgrep.hlp, revision 1.1

1.1     ! root        1: CPGREP.EXE
        !             2: 
        !             3: This program is compatible with Xenix fgrep.  It supports a subset
        !             4: of the fgrep options and has a couple of extensions.  It is tailored
        !             5: to the 286 (though it will run on an 8086) and DOS.  It is a family
        !             6: API application, so it will run in both real and protected modes.
        !             7: When running in protected mode, it uses three threads in order to
        !             8: do asynchronous I/O.  It is pretty fast.
        !             9: 
        !            10: cpgrep -? produces the following usage message:
        !            11: 
        !            12: usage: CPGREP [-?BElnvxy][-e][-f <file>][-i <file>][<strings>][<files>]
        !            13: -? - print this message
        !            14: -B - match pattern if at beginning of line
        !            15: -E - match pattern if at end of line
        !            16: -l - print only file name if file contains match
        !            17: -n - print line number before each matching line
        !            18: -v - print only lines not containing a match
        !            19: -x - print lines that match exactly (-BE)
        !            20: -y - treat upper and lower case as equivalent
        !            21: -e - treat next argument as the search string
        !            22: -f - read search strings from file named by next argument
        !            23: -i - read file list from file named by next argument
        !            24: 
        !            25: Extensions are -B, -E, and -i.  Multiple search strings can be
        !            26: specified on the command line, though the rules for doing so
        !            27: vary slightly from those of Xenix fgrep because of differences
        !            28: between sh and command.com.  With cpgrep.exe, any white space
        !            29: character acts as a separator in the strings argument on the
        !            30: command line; on Xenix with fgrep, only a newline will work.
        !            31: If one wishes to search for a pattern containing white space,
        !            32: use the -e switch.  When search strings are being read from
        !            33: a file, however, newline is the only separator, just as it is
        !            34: with fgrep on Xenix.
        !            35:                                        Pete Stewart
