$PATH question
 
If you have two scripts with the same name in different directories in $PATH, which one runs?

For example, I have /usr/bin/myscript.sh and /usr/local/bin/myscript.sh.


Code:
user@linux>echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
When I run myscript.sh, only one will get executed, but which one? How can I change that?

First is launched from "/usr/bin" because it is ealier in PATH variable than "/usr/local/bin". How to change depends on distribution. For example in Ubuntu you can edit PATH environment variable in file "/etc/environment" globally or in your home directory in ".profile" file for one user.

It reads from left to right. So it will consider the one that comes first. i.e. if your script is in /usr/bin and /bin both, then it will consider the one which is in /usr/bin.

FYI: An alias will be run before it looks in the PATH.

Which operating system are you using? This will help us tell you what command to use.

Cheers!
