What are some common shell command errors I might encounter?

Common shell command errors include 'command not found', 'permission denied', and 'syntax error'. Each has specific causes.

What does 'command not found' mean?

'Command not found' means the shell cannot locate the command you entered. This could be due to a typo or the command not being installed.

How can I fix a 'permission denied' error?

To fix a 'permission denied' error, you can check the file permissions with 'ls -l' and use 'chmod' to change them if necessary.

What should I do if I encounter a syntax error?

A syntax error usually means there's a mistake in your command structure. Double-check for missing quotes, parentheses, or incorrect command usage.
