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

Simple function to permanently add an alias to your profile.

Tested on bash and Ksh, bash version above.

Here is the ksh version: PERMA () { print "$@" >> ~/.profile; }

Sample usage:

PERMA alias la='ls -a'

What others think

Many Linux distros' ~/.bashrc files are configured to look for ~/.bash_aliases. to check yours, run:

grep aliases .bashrc

If you see something like this:

if [ -f ~/.bash_aliases ]; then

. ~/.bash_aliases

Then all you need to do to save aliases is:

alias > ~/.bash_aliases

alias >> ~/.bash_aliases

So as to keep any existing aliases.
