Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

I know this sound really wierd but this is exactly what happens. I have my .profile and .bashrc file set up in a way that the .bash_aliases file gets executed (checked it with a echo). I do not get any errors and the aliases have worked an another machine.

I use the following command to see what aliases are registered.

echo $(alias | cut -d '=' -f 1 | sort -u)

I put this in the .bash_aliases file and it showed my aliases. Then I put it in the .bashrc file right after the call of the .bash_aliases file. The amazing thing is that the aliases, that have just bein created and printed, have vanished! They do no longer exist!

To show it better I'm going to give you the output when I log in and the content of the files.

Output:

You are running your .bashrc in a subshell. Which exits.

Bad:

bash ~/.bashrc

You need to source the file.

source ~/.bashrc

or

. ~/.bashrc
