Reload .profile in bash shell script (in unix)?

Question

Hi all,

I'm new to bash shell scripting, and have come across a challenge. I know I can reload my ".profile" file by just doing:

. .profile

but I'm trying to the same in a bash script I'm writing and it is just not working. Any ideas? Anything else I can provide to clarify?

Thanks

Answer 1

The bash script runs in a separate subshell. In order to make this work you will need to source this other script as well.

Answer 2

Try:

#!/bin/bash
# .... some previous code ...
# help set exec | less
set -- 1 2 3 4 5  # fake command line arguments
exec bash --login -c '
echo $0
echo $@
echo my script continues here
' arg0 "$@"
