Ok.
I have many productive aliases set for myself, but I very frequently use `screen`. The only problem is, my aliases don't stick around when I use screen, they revert to the defaults.

As a matter of fact, I can't even find where those defaults are.
I looked (obivously) in my own .bashrc, and /etc/bashrc, and checked other bash files but they're not there!

Basically, I have ll definated as ls -laF instead of just ls -l among other things.
So why does screen reset it's definition? (And where in the hell are those normal defaults? [rm = rm -i, cp = cp -i, mv = mv -i, ll = ls -l, etc.])

Try looking in /etc/profile.
I have never had any problems with screen screwing up my aliases though. Do you define them in your .bashrc? If so, is .bashrc included in .bash_profile? If not you can make .bash_profile call .bashrc so .bashrc always will be parsed. Include this in your .bash_profile:Håkan

I have

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

In my .bash_profile.

Does it have to be source ~/.bashrc?
As you can see, mine is just .

In addition, yes, my .bashrc contains my alias definitions.

Well.. the file .bashrc is read by non-login shells, but screen is a login shell by default.. . so man bash states about that problem...

anyway .. try
ln -s ~/.bashrc ~/.bash_login
ln -s ~/.bashrc ~/.bash_profile

and screen should read your aliases etc..

no dice.
I even ended screen and re-started it just to make sure.

I checked /etc/bashrc and there's nothing in there to override the aliases, at least... not with aliases of it's own.

Anything else I should be looking for?

I've noticed some systems like to hide those defaults in /etc/profile.d

Check that directory. This is typical for RedHat/Mandrake systems.

yep. Found that out tonight browsing through other forums and threads and such.

I moved the /etc/bashrc call to the top of my .bashrc file, and then put MY aliases and such below it.

New problem, now the aliases aren't loading whenever I'm NOT in screen.
Obviously, logging in over SSH is a login shell, so why aren't my aliases being defined?

Everything else in the .bashrc is executed properly.

May I ~bump~ this? It's been 3 weeks, and I'd like to figure this out, but I don't understand why it's not alias'ing properly.

[edit]
As it turns out, there is unalias ls and unalias ll lines in my .bash_profile... and I swear to god I didn't put them in there.
Must have been my friend (root) toying with me .
Thanks everyone.
