Hi guys!
Id love some help in trying to build a bash script menu.
What Im trying to do is the following...

1. Run a bash script eg.menu.sh
2. When run, it presents the following information......

===============================
--------- BASH MENU: Menu.sh ---------
===============================
Execute the following commands by typing the correct number...

[1] Connect to fire's temp folder
[2] Connect to fire's backup folder
[3] Switch to fire's temp folder
[4} Switch to fire's backup folder
[5] Disconnect from fire's backup folder
[6] Disconnect from fire's temp folder

-----------------------------------------------------------------------------------------
3. The user types '1' to connect ot fire's temp folder for example.


4. The commands I have for this are:

----------------------------------------------
[1] Connect to fire's temp folder
mount -t cifs //192.168.2.3/fire_temp /mnt/net_temp_h_fire_fire_temp -v -o user=scripter,pass=password,domain=WORKGROUP,rw'

----------------------------------------------
[2] Connect to fire's backup folder
'mount -t cifs //192.168.2.3/fire_backups /mnt/net_backups_h_fire_fire_backups -v -o user=scripter,pass=password,domain=WORKGROUP,rw'

----------------------------------------------
[3] Switch to fire's temp folder
cd /mnt/net_temp_h_fire_fire_temp; clear; echo "===== h:\fire\fire_temp ====="; pwd; ls -ltra | more'

----------------------------------------------
[4} Switch to fire's backup folder
cd /mnt/net_backups_h_fire_fire_backups; clear; echo "===== h:\fire\fire_backups ====="; pwd; ls -ltra | more'

----------------------------------------------
[5] Disconnect from fire's backup folder
umount /mnt/net_backups_h_fire_fire_backups

----------------------------------------------
[6] Disconnect from fire's temp folder
umount /mnt/net_temp_h_fire_fire_temp

================
I will add more above, but i just want to get the general idea how you would build this menu.sh script, so that a menu is presented, and all you have to do is press a number for the option you want to be executed.
Any ideas greatly appreciated.

A slight revision to that, so that it treats the user input as a string rather than an integer, as you never know what they may type in.

hi

I'd rather use "case" than "if" in this approach.-, it makes the code much much more readable

Here's my modified version of mcuk_storm's answer:
 #!/bin/bash
 
function outputMenu {
cat > /dev/stdout <<DELIM

[6] Disconnect from fire's temp folder
[7] Exit Menu
DELIM
 
read USERCHOICE
clear
 
echo Executing your selected option...
echo
 
case $USERCHOICE in
        "1") mount -t cifs //192.168.2.3/fire_temp /mnt/net_temp_h_fire_fire_temp -v -o user=scripter,pass=password,domain=WORKGROUP,rw;;
        "2") mount -t cifs //192.168.2.3/fire_backups /mnt/net_backups_h_fire_fire_backups -v -o user=scripter,pass=password,domain=WORKGROUP;;
        "3") cd /mnt/net_temp_h_fire_fire_temp; clear;
                echo "===== h:\fire\fire_temp =====";
                pwd; ls -ltra | more;;
        "4")  cd /mnt/net_backups_h_fire_fire_backups;
                clear;
                echo "===== h:\fire\fire_backups =====";

esac

until [ "1" = "0" ]; do
        clear

They are both brilliant!

Guys I cant thank you enough.

Guys they work great. Can I just finish off by asking you both...

In the case example, what does the
esac
at the end of the case actually do?

What does the

until [ "1" = "0" ]; do

until 1 actually do?

You guys are great.
The until loop basically just loops forever, it will loop until 1 = 0 which will never happen.

In the case, esac marks the end of the case statement (the } at the end it a bit miss leading you may be mistaken for thinking that was the end of the case but it is the end of the function), so esac just says there are no more cases to be defined for that construct.
