Functions

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

Swap the two last arguments of the current command line

Swap the two last arguments of the current command line

Say you just typed a long command like this:

rsync -navupogz --delete /long/path/to/dir_a /very/long/path/to/dir_b

but you really want to sync dir_b to dir_a. Instead of rewriting all the command line, just type followed by , and your command line will read

rsync -navupogz --delete /very/long/path/to/dir_b /long/path/to/dir_a

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives

Know a better way?

If you can do better, submit your command here.

What others think

Nice. It's worth pointing out a few things.

@bibe: I'd add "readline" to the description (make it easier to search for).

Ctrl-E moves the cursor to the end of the line, but if you've just used up-arrow to alter the previous command the cursor will already *be* at the end.

You can replace Esc-T with Meta-T (or Alt-T) -- easier to type on many keyboards.

Unfortunately, readline seems to treat . (dot/period) as a separator:

echo hello wor.ld

becomes

echo hello ld.wor

Anyone know how to set the word break characters?

It does not appears to work in my Solaris 5.10 machine..!

@michaelrozar17 on my Commodore64 doesn't work either!

Funny and useful keybinding but can't see how you could swap whole paths as in your example.

- swaps *two* word (@flatcap swaps just *one* word AFAIK).

- readline treats '/' as a word on my boxes (Arch and Debian).

(sorry forgot cmdlinefu's code cleaner)
