cp !!

What Others Think

Wow, that's amazing. I'd suggest changing your description, though, from "entire command line" to "all the command line arguments" (because it doesn't include "cp"). Your example could also be represented as: cp /work/{host,target}/phone/ui/main.cpp ... but the search and replace makes it very interesting, very versatile.

it does include "cp"

That's... wow.

Ah, sorry. My mistake.

I didn't get this to work in ksh, but I did get it to work in bash.

Yes! I just wondered if something like this exists while doing "mkdir -p long/path && cd long/path"

Btw, this trick is somewhat ruined by the fact that bash saves the command expanded in history. Is there any flag to store it as such?
wipu · 373 weeks ago
to avoid "mkdir -p long/path && cd long/path" you can do: mkdir -p long/path and then do cd [ALT]+. (that means pressing the 'alt' key and the '.' simultaneously, it expands to the last parameter used :D)
