CPGREP.EXE
Created by Microsoft Corp. 1986

This program is compatible with Xenix fgrep.  It supports a subset
of the fgrep options and has a couple of extensions.  It is tailored
to the 286 (though it will run on an 8086) and OS/2.  It is a family
API application, so it will run in both real and protected modes.
When running in protected mode, it uses three threads in order to
do asynchronous I/O.  It is pretty fast.

cpgrep -? produces the following usage message:

usage: CPGREP [-?BElnvxy][-e][-f <file>][-i <file>][<strings>][<files>]
-? - print this message
-B - match pattern if at beginning of line
-E - match pattern if at end of line
-l - print only file name if file contains match
-n - print line number before each matching line
-v - print only lines not containing a match
-x - print lines that match exactly (-BE)
-y - treat upper and lower case as equivalent
-e - treat next argument as the search string
-f - read search strings from file named by next argument
-i - read file list from file named by next argument

Extensions are -B, -E, and -i.  Multiple search strings can be
specified on the command line, though the rules for doing so
vary slightly from those of Xenix fgrep because of differences
between sh and command.com.  With cpgrep.exe, any white space
character acts as a separator in the strings argument on the
command line; on Xenix with fgrep, only a newline will work.
If one wishes to search for a pattern containing white space,
use the -e switch.  When search strings are being read from
a file, however, newline is the only separator, just as it is
with fgrep on Xenix.
