Path environmental variables are variables that function like a shortcut for your system. They allow you to define directories where executables are located.
Assume you installed this application picc-9.82.9453-linux.run. Without setting the path you’d have to run this every time in your terminal:
Running picc without having to define the path every time is so much easier, and faster. To achieve this experience you have to add the application executable to the Path environmental variable.
The first option is edit your user profile:
$ vim ~/.bash_profile
It will look something like this:
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export PATH
You are looking to edit this section:
Update the path with new application location (e.g., /usr/hitech/picc/9.82/bin) using the colon (:) as the separator.
Save the file, and try running the command in your terminal.
Sharing is caring!
