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
