# Launching POSTFEKO (Linux)

There are several options available to launch POSTFEKO in Linux.

Launch POSTFEKO using one of the following workflows:
• Open POSTFEKO using the Launcher utility.
• Open a command terminal. Launch POSTFEKO using the absolute path to the executable in the installation, for example:
/home/user/2022.1/altair/feko/bin/postfeko
• Open a command terminal. Source the initfeko script using the absolute path to it, for example:
. /home/user/2022.1/altair/feko/bin/initfeko
Sourcing initfeko ensures that the correct Feko environment is setup. Type postfeko and press Enter.
Note: Take note that sourcing a script requires a dot (".") followed by a space (" ") and then the path to initfeko in order for the changes to be applied to the current shell and not a sub-shell.
