Thanks for the reply, and I like that ability to use standard input! I tried the following, and the output from -L and -l seems almost the same, except for that extra line that says "(standard input)" when I use the -l option. Any further clarification / clues would be appreciated. <quote> rhk@s19:/rhk/ked1$ grep -l test - one two test (standard input) rhk@s19:/rhk/ked1$ grep -L test - test rhk@s19:/rhk/ked1$ grep -L test - one two test rhk@s19:/rhk/ked1$ grep -l test - one two test (standard input) rhk@s19:/rhk/ked1$ </quote>
