Understanding exit codes on Linux
2024-10-04
Whenever you run a command in a Linux terminal, a numeric exit code is generated – even if you see no sign of it.
The code reports the success or failure of the command.
And, if the command fails, it provides a value that hints at the problem.
If the exit code is 0, all is well.
You will just see the normal output from the command you ran.
Otherwise, you should see some type of error reported – like “permission denied” or “command not found”.
If you want to display the numeric exit code, you can use the echo $? command as shown in the examples below.
