Unix bash alias not working after start screen

Hi I am having a problem with setting alias in mac after I start the screen command, I have alias for working with git, like 

commit=git commit

they work as I expect when I start my terminal (iTerm2), but then sometimes I use screen to have simultaneous instances in remotes servers and virtual machines I work with. After this the alias disappear(command not found).

Does anyone know why or how solve it?

You need to make sure your aliases are defined in ~/.bashrc to ensure they get included in all logins. You can test this out: edit your ~/.bashrc to include this line:

echo "bashrc"

And then edit your ~/.bash_profile to include this line:

echo "bash_profile"

You'll see when you start screen that only "bashrc" is displayed.

See this question for much more detail on the subject.

To make the alias work, you must use the alias command. For example, to create an alias in Bash you do:

$ alias commit="git commit"

This works temporarily ie.: in your current shell. In order to make it "stick", you must put it in your ~/.bashrc. That will make it be sourced to all instances of Bash you'll invoke during your terminal session.

When you start screen, it starts a separate Bash too, so you'll be covered.

You write something about VMs. If you need this alias to work there, you must make ~/.bashrc on these VMs to have the same aliases. But that's the other story. You should already know how to achieve what you want.
