My Custom Linux Scripts Index
This page tracks custom scripts I’ve written or installed on my systems, primarily placed in /usr/local/bin for global use. Each script is either a utility, security tool, or automation helper I use regularly.
📁 Script Directory: /usr/local/bin
This directory is in the system $PATH and allows me to run any executable script from any location in the terminal.
To make a script globally accessible:
sudo mv myscript.sh /usr/local/bin/myscript
sudo chmod +x /usr/local/bin/myscript
Then simply run:
myscript
