Command line globbing! For the uninitiated: Let's say my pwd is `/home/projects` and i want to edit `/home/projects/a_huge_sprawling_app/940j_394/lol/flight_controller.rb` `vim **/flight_controller.rb` opens our flight_controller.rb straight away. In terms of effort, this allows you to basically omit a `find -name` when you're in a rush to edit some damn file where the hell is it again damn we need to reevaluate this directory str... ---- Double bang to re-use your last terminal entry. One great use, taking all the pain out of forgetting your sudos `rm -rf /var/log` rm: cannot remove `/var/log': Permission denied `sudo !!` All evidence of wrongdoing is now destroyed. ----- Ok, here is an awesome one for users of the ultimate cloud IDE: Vim. In your local ~/.ssh/config: `ForwardX11 yes` `SendEnv WINDOWID` In your remote server's /etc/ssh/sshd_config: `AcceptEnv WINDOWID` In your vimrc: `set clipboard=unnamedplus` This has the effect of seamless yank and paste between local and remote vim sessions, no need for ctrl+shift+v. I love linux.

FWIW, the double-star recursive globbing was added in Bash 4.0. My reading of the manual[1] suggests it is disabled by default, and can be enabled by setting the 'globstar' shell option. I believe it's enabled by default in zsh. [1]: https://www.gnu.org/software/bash/manual/bash.html#The-Shopt-Builtin https://www.gnu.org/software/bash/manual/bash.html#The-Shopt...

  Thanks. Sometimes I forget that zsh is not what everyone uses. I should add zsh to the list, hah!

  I just tried it on bash 4.2.25, and it worked, even though I just learned about it. Maybe not every OS enables the same default options for Bash (I'm using Lubuntu 12.10 at the moment)

    Yep, that is a fair point. I should have qualified my statement about bash's defaults, since many OSs include their own custom start-up files that may modify the defaults.

Re: command line globbing with globstar -- is there some way to get it to cache filepaths that are frequently accessed? It's quite slow for me (I usually use aliases for that, which I was contemplating getting rid of). Thanks a lot for wising me up to the new hotness offered by bash 4+ (zsh is also pretty slow for me for some reason, even though people keep telling me to switch to that. Maybe I'm more impatient than most folks).

  Sorry for the late reply. No built in way to cache globbed filepaths as far as I know. I did a little googling but to no avail. I suspect it wouldn't be too complicated to hack something together though. Another potential option: buy an SSD.
