  • Add this line to your ~/.gitconfig for a git alias "git brd" (i.e., brd = (br)anch+(d)ate) which sorts branches by date. Allows you to pass in limited "git branch" options such as "-r" (remote) or "-a" (all). (Note: forum added "$" prefix to command; obviously in gitconfig there is no "$" prefix.) Show Sample Output

    brd = "! f() { for k in $(git branch $@ | sed 's/^..//; s/ .*//'); do echo "$(git log -1 --pretty='%Cgreen%ci %Cblue(%cr)%Creset ' $k) $k" ; done | sort -r; }; f"

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. 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.

Check These Out

Remount an already-mounted filesystem without unmounting it
Necessary for fsck for example. The remount functionality follows the standard way how the mount command works with options from fstab. It means the mount command doesn't read fstab (or mtab) only when a device and dir are fully specified. After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command. It does not change device or mount point.

Viewable terminal session over network.

Find Files That Exceed a Specified Size Limit

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

print all characters of a file using hexdump
'od -c' works like 'hexdump -c' but is available on other operating systems that don't ship with hexdump (e.g. solaris).

Create A Continuous Yahoo! News Ticker For The Terminal
This creates a permanent stock ticker in the terminal. it has scrolling action and refreshes when each cycle is done to get the latest news.

SSH to a machine's internet address if it is not present on your local network
Ping machine once, waiting 1 second for response until failing. Upon fail, ssh globally, otherwise ssh locally.

Run TOP in Color, split 4 ways for x seconds - the ultimate ps command. Great for init scripts
One of my favorite ways to impress newbies (and old hats) to the power of the shell, is to give them an incredibly colorful and amazing version of the top command that runs once upon login, just like running fortune on login. It's pretty sweet believe me, just add this one-liner to your ~/.bash_profile -- and of course you can set the height to be anything, from 1 line to 1000! $ G=$(stty -g);stty rows $((${LINES:-50}/2));top -n1; stty $G;unset G Doesn't take more than the below toprc file I've added below, and you get all 4 top windows showing output at the same time.. each with a different color scheme, and each showing different info. Each window would normally take up 1/4th of your screen when run like that - TOP is designed as a full screen program. But here's where you might learn something new today on this great site.. By using the stty command to change the terminals internal understanding of the size of your terminal window, you force top to also think that way as well. # save the correct settings to G var. $ G=$(stty -g) # change the number of rows to half the actual amount, or 50 otherwise $ stty rows $((${LINES:-50}/2)) # run top non-interactively for 1 second, the output stays on the screen (half at least) $ top -n1 # reset the terminal back to the correct values, and clean up after yourself $ stty $G;unset G This trick from my [ http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html bash_profile ], though the online version will be updated soon. Just think what else you could run like this! Note 1: I had to edit the toprc file out due to this site can't handle that (uploads/including code). So you can grab it from [ http://www.askapache.com/linux-unix/bash-power-prompt.html my site ] Note 2: I had to come back and edit again because the links weren't being correctly parsed
