Repeat the previous command but with a string replacement 

^geomtry^geometry

November 4, 2011 — bashoneliners

Explanation

This can be very useful for example after a mistyped command like this:

convert -crop 745x845+0+150 my_logo.png -geomtry 400x my_logo2.png
^geomtry^geometry

"-geomtry" should have been "-geometry", the one-liner above will re-run the command with a replacement that fixes the typo.
