I used to do !$ a lot until I configured iTerm to allow me to cycle through the last args with alt-. which is way faster. But I did not know about the colon modifiers, so !$ might make its way back into my workflow. ZSH gives me a nice overview of what's possible: > !$:<tab> & -- repeat substitution A -- absolute path resolving symbolic links Q -- strip quotes a -- absolute path c -- PATH search for command e -- leave only extension g -- globally apply s or & h -- head - strip trailing path element l -- lower case all words q -- quote to escape further substitutions r -- root - strip suffix s -- substitute string t -- tail - strip directories u -- upper case all words
