I need to start using GIT for my projects from now on and I need to use some UNIX commands. but no matter what I do, I always receive "command not found" error.

I installed MacPorts, but still cant run any UNIX command :/

When I try ls, I get the error below, same for sudo, or any other command:

-bash: ls: command not found

and when I try $PATH, I get the lines below:

hakan-yilmaz-MacBook-Pro:~ hakanyilmaz$ **$PATH**

-bash: /opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/2.6/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:/opt/subversion/bin/:PATH: No such file or directory

I'm on Mac OS X 10.6.6

I spent 2-3 days and kept googling and trying everything I found at forums, but no success.

SOLUTION:

I opened .bash_profile with TextWrangler and removed everything else than

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

Then, I reboot that Mac, and WORKING!!!!
