source not working from within shell script

Question

I have the following line in a shell script:

source bash_profile

It does not error, but it does not do anything that I can see either (It's not reloading my aliases like I expect)

However, from the same folder that the shell script is in, if I just run the command from the shell, it works like I expect.

I never change directories from within the script either. In fact, here is the script:

direction="to"
destination="local"
if [ -n $1 ]
    then
    direction=$1
fi
if [ -n $2 ]
    then
    destination=$2
fi

command=$direction$destination

if [ $command = "fromlocal" -o $command = "togit" ]
    then
    cp /c/Program\ Files/Git/etc/bash_profile /d/automata/flgitscripts/bash_profile
else
    cp /d/automata/flgitscripts/bash_profile /c/Program\ Files/Git/etc/bash_profile
fi

source /c/Program\ Files/Git/etc/bash_profile

I use the script to manage changes to and from the bash_profile and store them in a git repo.

Why isn't the source command working from within the shell script?

Answer 1

Are you sourcing the script too: source thescriptname? Otherwise the script is running in a new shell and the source bash_profile command affects that new shell (which exits at the end of the script).
