how can I search with context lines from above/below? I'm trying to mimic the old DEC VMS "Search /win=(3,10) stringToFind filelists.*" functionality. This little trick makes _every_ ascii file into a database, so I hope you can help me! (I'm on Mac OSX 10.2.4 unix, with the default shell of tcsh, but I could change that)

from 'man grep' (GNU Project edition, other versions may be different; SunOS 5.9 grep doesn't seem to have any of these options) OPTIONS -A NUM, --after-context=NUM Print NUM lines of trailing context after matching lines. Places a line containing -- between contiguous groups of matches. -B NUM, --before-context=NUM Print NUM lines of leading context before matching lines. Places a line containing -- between contiguous groups of matches. -C NUM, --context=NUM Print NUM lines of output context. Places a line containing -- between contiguous groups of matches.
