Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

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"

Comment by kev 266 weeks and 1 day ago

That's... wow.

Comment by kaedenn 266 weeks ago

Ah, sorry. My mistake.

Comment by flatcap 266 weeks ago

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

Comment by hellspawn 266 weeks ago

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

Comment by wipu 265 weeks and 6 days ago

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?

Comment by wipu 265 weeks and 6 days 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)
