There is a DOS 'grep' from way back in the '80s where there was a library of
many standard UNIX comands for DOS. Each time I get a new computer the first
thing I do is download all the programs. Here is the "grep /?" response:
Name: grep - regular expression search through files
Usage: grep [ -vclins? ] <pattern> file1 ...
Version: 2.0 for PCs with DOS 2.1 and higher

The options for grep are:
-v: print the lines that DON'T match the pattern
-c: print a count of the number of matches in each file
-l: print the name of each file that has a match
NOTE: options v, c and l are exclusive. Only one of these may be selected
-i: ignore the case of each character while matching
-n: print the line number that the match occurred on
-s: do not report errors encountered while opening or reading files
-?: print this description of the program.
