Pattern: Invalid argument to sudo
Issue: -
Due to the Unix process model, sudo can only change the privileges of a new, external process. It cannot grant privileges to a currently running process.
This means that shell builtins - commands that are interpreted by the current shell rather than through program invocation - cannot be run with sudo. This includes cd, source, read, and others.
Instead you can run a shell with sudo, and have that shell run the builtins you want:
sudo sh -c 'cd /root && pwd' # This shows /root
pwd # This shows the original directory
Example of incorrect code:
sudo cd /root
pwdExample of correct code:
sudo sh -c 'cd /root && pwd'
