Scripts tips

📜

To run a script directly (./script.sh), it needs the execute bit. 755 makes it executable by everyone; 700 keeps it private to you.

💡

For scripts in a shared bin directory, 755 is standard. For personal scripts with sensitive logic, use 700.

🎯

After making it executable, verify with the symbolic output here — you want an "x" in the owner triad at minimum.
