I'm having trouble understanding all of your questions. However, below, I modified the TEST_A select by placing it inside a while loop. Now, an illegal choice forces the TEST_1A select to execute again. Maybe with this information, you can answer your other questions. Let me know if you have any other questions. #!/bin/bash echo " ++++Plese select the TEST " test_a_select=0 select TEST in "TEST_A" "TEST_B" do case $TEST in TEST_A ) echo " Please select (1-3) " while [ $test_a_select -eq 0 ] do # inserted while loop select TEST_1A in "good" "bad" "EXIT" do case $TEST_1A in good) echo " It is good" exit 0 ;; bad) echo " It is bad" exit 0 ;; EXIT) exit 0 ;; *) echo " Bad choise" break ;; esac done done ;; TEST_B ) echo " Please select (1-3)" select TEST_B2 in "average" "middle" "EXIT" do case $TEST_B2 in average) echo " It is average" exit 0 ;; middle) echo " It is middle" exit 0 ;; EXIT) exit 0 ;; *) echo " Bad choise" break ;; esac done ;; * ) echo " Invalid choice " exit 0 ;; esac done

@OP whenever you need to "go back" to some part of the code, you put loops. Use a while loop and put your selects inside the loop.

Thanks for your help..
