Modified: gnu/usr.bin/grep grep.c
Log:
grep -q pattern file
search 'pattern' in whole file 'file', from top to bottom. This is
not necessary; if grep found 'pattern' it can stop further searching
in file 'file'.
Example:
$ time ./grep-old -q Adam /usr/share/dict/*
1.93 real 1.05 user 0.85 sys
$ time ./grep-new -q Adam /usr/share/dict/*
0.14 real 0.06 user 0.06 sys
