Create a Simple Script
Let's create a script that tells you useful info about your Mac.
1
Create the file:
touch ~/myinfo.sh
2
Open it in TextEdit:
open -e ~/myinfo.sh
3
Add these lines:
#!/bin/zsh
echo "Current folder:"
pwd
echo ""
echo "Files here:"
ls
4
Save and close TextEdit
What's #!/bin/zsh? This first line (called a "shebang") tells your Mac which program should run the script. For Mac, use zsh.
Key Takeaway
Scripts start with #!/bin/zsh and contain commands, one per line.
