Not always sure =>which one in which to put system wide changes. The .bash_profile runs when you first log in. It then sucks in the .bashrc. The .bashrc is sucked in automatically by subshells. So the answer is to put all of your environment variable definitions in the .bash_profile so they can be inherited by all of the subprocesses. The one exception to the rule is if you need to use rsh. Then be aware that remote jobs do *not* go through the .bash_profile and instead jut use the .bashrc. So what's a girl to do? Simple: Just check in your .bashrc to see if you're interactive by seeing if your PS1 variable is no set. If it is not set then just source in your section of your .bash_profile that sets those variable. Is that clear? -- -Time flies like the wind. Fruit flies like a banana.
