从.bashrc脚本中止

Question

I know the .bashrc script must be run like source .bashrc or . .bashrc . .bashrc so changes in exports are kept during the session, but i need to abort from half the bashrc script without exiting the session.

Currently i'm doing a binary search of a point where i issue a command which assumes the existence of a tty. This is to avoid getting the message stdin: is not a tty . So the easiest way is to break the execution of the bashrc script, but i haven't found a way to do so.

How do i abort from half the execution inside the .bashrc script w/o ending the session ? (aka using the exit command)

Answer 1

You can use the return command to "exit" your script. It's usually an error to use return outside of a function, but you can think of the entire script as a function if it is being source d.

Answer 2

what about

if [ yourbreakcondition ]; then
    ...
else
   ...
   The rest of bashrc here
   ...
fi

Answer 3

Just call return within your bashrc.

Example

if [ true ]
then
    return
fi
