My award for the single linux command line tip that I wish I'd known about years earlier: cd - (cd followed by a single dash). It takes you to $OLDPWD. Another great one is ^foo^bar^ which will repeat the most recent command but substitute the string "bar" for "foo". e.g. pw@kermit pw $ find . -name "*pyc" -exec ls -l {} \; >> stuff_of_interest pw@kermit pw $ ^pyc^pyo^ find . -name "*pyo" -exec ls -l {} \; >> stuff_of_interest (Notice that it only does one substitution on the line.) And while I'm at it, two commands I find REALLY handy which may not be installed by default: seq(1) and rename(1). -- Paul Winkler http://www.slinkp.com Look! Up in the sky!
