Reversing exports?

[HamsterOfDoom]

Soooo.... New Linux Newbie joining this place... I've been brushing up from my old DOS days at the command line using this set of tutorials (as well as using them to teach myself Linux).

Writing shell scripts - Lesson 1: Writing your first script and getting it to work

They had me create a simple hello world script (titled my_script). I did it. It wouldn't execute without an absolute or relative path. Then they told me the following:

One of the instructions was to edit my .bash_profile or .bashrc, adding an export of ~/bin/ to my path variable. It worked as intended, and that was great. Hurray I know how to automate some environment changes!

But uh oh. I removed the export line from both .bash_profile and .bashrc, expecting to be unable to run the script with a simple "my_script" command. I was mistaken. Echoing the $PATH variable revealed that $HOME/bin was still in my path, which I could swear was not there before... (if it were, I would not have failed prior to editing .bash_profile and .bashrc). So my question is how on earth do I get rid of it? It's nice to know how to do something, but if you can't undo it... Should you really be doing it in the first place?

I've looked around in /etc/*.* for anywhere that is adding that to my path and I can't find it.

Thanks in advance for your help!

Hi and Welcome !

you have to regenerate PATH variable.

either logout and login back, ( if you are using X, just close Terminal/Konsole and open it again )

OR execute this

source .bashrc

No go. executing source .bashrc leaves \home\[my-user-name]\bin in the path variable. I'm testing to see what happens when I remove /bin from my home directory (seems reasonable that it would add this outside .bash_profile and .bashrc if the directory exists). Tell ya how it turns out.

Yeah - that was why it was hanging around. Some script somewhere must be detecting if $HOME/[user]/bin exists, and if it does, adding it to $PATH.

Thanks for the reply though, it moved me in the right direction!
