Question
Which command should I use to display the exit code of the previous command?echo ?echo CODEecho $EXITCODE
Solution
You should use the command echo $? to display the exit code of the previous command in Unix or Linux. This command will print the exit status of the last executed command to the terminal. The exit status is a numerical value that represents the success or failure of the command. A zero exit status indicates success, while a non-zero exit status indicates failure.
