export PATH=$PATH from shell script
Why doesn't export work in shell scripts?

One more question ... why is it that if I run this from pterm it works ...

export PATH=$PATH:/my/add/on

When I do the same thing in a shell script, it doesn't work. Try it, and you will see. Anyone know why? I have been told that its because when I run it in a script, the variable is not treated as a global one. But I have read instruction s on doing this for global defined variables.

I have tried this so many ways and it fails. If I type it out at pterm it sticks. The same thing put into an .sh file and it fails. Frustrating!

Basic UNIX:

Use the dot operator to source a script rather than launching it as a child process.

In other words, do this to call your script:

# . ./foo.sh

instead of this:

# ./foo.sh

Keep on hacking!

Thank you!
I had been having this same problem. I 'knew' the answer, that the script needed to be sourced, but I didn't know to use the '.' command.

Ah yes, that worked wonderfully. Thank you so much. That has been driving me crazy for DAYS. And every time one of my experiments caused a memory leak and I had to reboot Audrey, I would have to re-enter a long string of env variables. Now my script runs nicely.

Thanks!!!

Glad to be of help! In return, I demand that you continue hacking your Audrey and continue sharing your results here!

Me? I just hosed mine up trying to add LibC to the .cmp directories without compressing it. I added it to boot.sh and rebooted... Uh oh! No boot! So I flashed an image from my OTHER Audrey and all's better. Live and learn...
