commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):
Subscribe to the feed for:
vix /tmp/script.sh
Open a file directly with execution permission.
Put the function in your .bashrc
You can also put this in your vimrc:
command XX w | set ar | silent exe "!chmod +x %" | redraw!
and open a new file like this:
vi +XX /tmp/script.sh
Also works with:
chgrp --reference file1 file2
chown --reference file1 file2
sometimes if directories are too deep, chmod -R fails... in those cases, a find comes in most handy :)
Makes any files in the current directory (and any sub-directories) group-readable.
Using the "! -perm /g=r" limits the number of files to only those that do not already have this property
Using "+" on the end of the -exec body tells find to build the entire command by appending all matching files before execution, so invokes chmod once only, not once per file.
"find . -type d -print0 | xargs -0 chmod 755"
