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.
