Learning BASH 4
Carrying on from my previous post – http://zleap.net/learning-bash-3
Just looking at the Bash Programming How_to, this is a great document despite being nearly 20 years old.
in Section 9 – user interfaces there is the following program
#!/bin/bash OPTIONS="HELLO QUIT" select opt in $OPTIONS; do if["$opt"="QUIT"];then echo done exit elif["$opt"="HELLO"];then echo"Hello, World" else #clear echo"bad option" fi done
This works really well only the user get told the repl.it process died unexpectedly.
I managed to fix this by altering the program very slightly. In the example below remove the exit statement
Again if needed, a direct link https://repl.it/@zleap/bashmenush
I have also made this a little more friendly by adding this as line 2
echo “Please choose an option”
I think this probably demonstrates key skills such as problem solving.
Please feel free to discuss further via the repl.it forums or via twitter @zleap2018. You may also want to follow @replit.
