file : ~/.bash_profile (.bash_profile)
Whenever I create a new screen session on my Mac, the terminal window would display
bash: git_color: command not found
bash: git_branch: command not found
Why is the function git_color and git_branch is not getting executed on the screen session?
Is there any alternative to achieve it?
I am not entirely sure about how screen works.
What seems is that .bash_profile doesn't get executed as screen is not creating a login shell. [1]
Going by the general bash rules, PS1 is being read by the shell issued by screen because you exported it.
i.e., you did this:
export PS1
Do the same for your functions. [2]
Add 2 commands to your .bash_profile after you have defined both the functions:
export -f git_color
export -f git_branch
Alternatively, add those functions and PS1 to .bashrc as well.
