I couldn't find "-fF" in my Unix books or "man grep", but putting up to three "-ve" reduces the number of times I have to run it by nearly a third. Also runs faster.
Thank you, gentlemen.
I've used the command file for sed many times, but not grep.
Recent versions of grep have a -E option (to specify using extended regular expressions in patterns instead of the default basic regular expression) and a -F option (to specify using fixed strings instead of regular expressions in patterns).
Older versions of grep had an fgrep utility that behaved like newer versions behave with grep -F and older versions of grep had an egrep utility that behaved like newer versions with grep -E.
The -f file option and option-argument have been specified for a long time but might not have been around when SCO UNIX was in active development. On systems that have a -f option, -f file specifies using a file named file to get a list of patterns instead of (or in addition to) getting them from the command line.
Note that if you use an option that requires an option-argument, that option must be specified last if you combine a group of options in one command-line argument. The command-line:
is a request to print lines from standard input that do not match (-v option) fixed strings (-F option) found in the file named file (-f file option and option-argument).
On the other hand the command-line:
is a request to print lines from the file named file (an operand on the command-line) that do not match (-v option) found in the file named F (-fF option and option-argument).
For SCO UNIX, I would suggest that you try:
The egrep uses EREs instead of BREs for the pattern (which allows you to use | as a separator between alternatives in a single pattern) instead of specifying multiple patterns with -e options. The length of a command-line given to the shell is essentially unlimited, but if you're creating a script you may be using an editor that limits line lengths to about 2,048 bytes per line. That should be more than enough to create a pipeline that won't break active process count limits even if the SCO UNIX egrep doesn't have a -f option.
