I have put an echo in three profile scripts that shows the file name so that I can see the order they run.

When I log in I see.

$ alias ls
alias ls='ls --ignore=*.pyc --color'

Yet when I start a screen session I see

$ alias ls
alias ls='ls --color=tty'

The alias I've set up in ~/.bashrc is being overwritten by color-ls but only within screen, is there any round this annoying behaviour?

You should first read man bash (section 'INVOCATION') about when which file is actually used.

Your little 'trace' shows you that your ~/.bashrc always sources /etc/bashrc which is then calling color-ls ... or not, depending on code in /etc/bashrc as it seems.

So, two ways to solve the problem:

  • Check, under which circumstances /etc/bashrc decides to not source color-ls.
  • Setup your aliases after your ~/.bashrc processes /etc/bashrc.
