Is it possible to set PATH on Mac OS X Lion without restarting?

Question

Is there a way to set the PATH on /etc/paths without the need to reboot your Mac? I know I can do it using an alias but it's not permanent.

For example, I want to set the PATH for MySQL.

Answer 1

I assume you want the PATH variable to be set in your terminal environment. If you are using bash (default on Mac OS X) you can add

export PATH=${PATH}:/your/path/to/mysql

to your .bashrc file in the home directory

Answer 2

It is not possible to update the system-wide path.

You can execute the line specified by @Matteo though (without needing to add to .bashrc / .bash_profile) and then launch all applications from Terminal. They will inherit the modified $PATH value.

Answer 3

Why can't you set the path in /etc/bashrc? Seems like this would be system-wide.

Answer 4

Straightforward way to edit PATH env variable for Terminal mode:

(This is just a different way to do what is mentioned above in case you don't have R/W permission, as I did not)

Navigate to the /private/etc/paths in Finder, r-click, Get Info, Select Sharing & Permissions, change Everyone to Read & Write, edit and save the file (append the new path to the end of the list), then restore the permissions if necessary.
