What does the then in linux mean? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

The word then means later in English. In linux, then is a structured command that is used in conjunction with if. The most basic if-then structure is if commond then commonds fi, in which the successful execution of the statement after if will jump to the statement after then, otherwise it will not jump.

The most basic if-then structure:

If commond then commondsfi

In shell, it is based on the exit status of the command. If the command is executed successfully, the status is 0, then the command after then is executed, and if the command is not executed successfully, the status is 0

Otherwise, commands that follow the then will not be executed. Bash shell moves to the next command of the script.
