Check These Out
Usage: upto directory
Alias a single character 'b' to move to parent directory. Put it into your .bashrc or .profile file.
Using "cd .." is one of the most repetitive sequence of characters you'll in the command line. Bring it down to two keys 'b' and 'enter'.
It stands for "back"
Also useful to have multiple:
alias b='cd ../'
alias bb='cd ../../'
alias bbb='cd ../../../'
alias bbbb='cd ../../../../'
Something to stuff in an alias when you are working in multiple environments. The double-pipe OR will fall through until one of the commands succeeds, and the rest won't be executed. Any STDERR will fall out, but the STDOUT from the correct command will bubble out of the parenthesis to the less command, or some other command you specify.
This will generate the same output without changing the current directory, and filepath will be relative to the current directory.
Note: it will (still) fail if your iTunes library is in a non-standard location.
gpg command to encrypt a file on the command line.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
Running this command turns shell tracing and shell verbose debugging on or off. Not only does it do that, it also uses your terminals builtin method of setting colors to make debugging much easier.
It looks at the current shell options contained in the $- special bash variable and that lets this function set the opposite of the current value. So from the shell you could do a:
$ setx; echo "y" | ( cat -t ) | echo "d"; setx
and it will turn on debbuggin.
This is an amazingly useful function that is perfect to add system-wide by adding it to /etc/profile or /etc/bashrc.. You can run it from the shell, and you can also use it in your shell scripts like my .bash_profile - http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html
Pump up the chatter, run this script on a regular basis to listen to your twitter timeline.
This is a rough first cut using several cli clips I have spotted around. There is no facility to not read those things already read to you. This could also easily be put in a loop for timed onslaught from the chatterverse, though I think it might violate several pointsof the Geneva Convention
UPDATE - added a loop, only reads the first 6 twits, and does this every 5 mins.
recursively deletes all broken symlinks using zsh globbing syntax.
