Before Pull: Make .sh scripts executable (chmod quick reference)

Goal	Command	Notes / When to use
Make one script runnable	chmod +x script.sh	Most common – adds execute for owner/group/others
Owner only	chmod u+x script.sh	Safer on shared servers
Everyone	chmod a+x *.sh	Or chmod +x *.sh (same)
Standard for scripts in repo	chmod 755 script.sh	rwxr-xr-x – owner full, others read+exec
Fix many at once	find . -name "*.sh" -exec chmod +x {} \;	Recursive in current dir
Check current perms	ls -l script.sh	Look for x in permissions

Tip: Always have #!/usr/bin/env bash (or #!/bin/bash) as first line.
