Is it possible to coerce bash to reload the .profile file without logging out and back in again?
This should work for the current terminal:
. is a
bash builtin and a synonym for
. filename [arguments]
source filename [arguments]
Read and execute commands from filename in the current shell environment (…).
If you don't want to start a new shell but execute the script in the current shell, you source it:
source built-in is a synonym for the Bourne shell
. (dot) command.
