Next Steps
As you become more comfortable with these basic commands, you might want to explore:
Command line text editors like Nano, Vim, or Emacs
Writing simple shell scripts to automate tasks
Package managers like apt (Linux), Homebrew (Mac), or Chocolatey (Windows)
Environment variables and how to set them
SSH to connect to remote computers
Common Mistakes and Troubleshooting
Command not found: Check spelling or ensure the command is available on your system
Permission denied: You may need administrator/root privileges
Windows: Run Command Prompt as Administrator
Mac/Linux: Use sudo before commands that need elevated privileges
No such file or directory: Double-check path and file names
Operation not permitted: Similar to permission denied, you might need special permissions
Tasks Windows Mac/Linux Current location cd pwd List files dir ls Change directory cd dir cd dir Create directory mkdir dir mkdir dir Create file type nul > file touch file Copy file copy source destination cp source destination Move/rename move source destination mv source destination Delete file del file rm file Delete directory rmdir /s dir rm -r dir Clear screen cls clear Get help help command man command
