Question
Which command should I use to display the exit code of the previous command?
Solution
You can use the command echo $? in the terminal to display the exit code of the previous command. Here are the steps:
- Open your terminal.
- Run the command you want to check.
- After running the command, type
echo $?and press enter. - The terminal will then display the exit code of the previous command.
The exit code is a way for a command to report back whether it succeeded or not. An exit code of 0 usually means that the command was successful, while any other number indicates there was some kind of error.
