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
