(II) An OR list has the form command1 || command2 command2 is executed if and only if command1 returns a non-zero exit status. The return status of AND and OR lists is the exit status of the last command executed in the list. In the following example: esoriano@omac:~$ sleep 10 || echo hey ^Z [5]+ Stopped sleep 10 hey esoriano@omac:~$ there are two different issues: (I) echo is executed when sleep is suspended, i.e., command2 is executed before command1 exits. (II) the exit status of command1 (when the job is resumed) will be 0 and command2 is (was) executed.
