Bash Script error in Debian?

Questions
1

Strange!
can’t seem to get an array going?

Running the script:
sh bin/readTest.sh

Debian 12 responds:

*Enter Fullname:  Jeff Pro*
  • Welcome Jeff Pro.*
  • bin/readTest.sh: 6: Syntax error: “(” unexpected*

I am getting getting other errors as well that are right of the man bash.

I have a menu driven script that works fine in Arch but not Debian?

#!/bin/bash

echo -n "Enter Fullname: "
read fullname
echo “Welcome $fullname.”
myArray=(“cat” “dog” “mouse” “frog”)

for str in ${myArray[@]}; do
echo $str
done

for i in ${!myArray[@]}; do
echo “element $i is ${myArray[$i]}”
done

Code works fine, looks fine. I am on PoP 22.04

Which version of Debian? I’ve got a Debian 10 vm which runs it ok.

john@debian:~$ cat /etc/os-release
PRETTY_NAME=“Debian GNU/Linux 10 (buster)”
NAME=“Debian GNU/Linux”
VERSION_ID=“10”
VERSION=“10 (buster)”
VERSION_CODENAME=buster
ID=debian
HOME_URL=“https://www.debian.org/”
SUPPORT_URL=“Debian -- User Support”
BUG_REPORT_URL=“https://bugs.debian.org/”

john@debian:~$ bash test.sh
Enter Fullname: Joe Blow
“Welcome Joe Blow.”
“cat”
“dog”
“mouse”
“frog”
“element 0 is “cat””
“element 1 is “dog””
“element 2 is “mouse””
“element 3 is “frog””

FWIW, which version of bash on your Debian box?

john@debian:~$ bash -version

@Narcosis @mcron
Debian 12
I put together a tester with a related error:
Was using an array to hold the choices and got the earlier noted error on Deb12.
Keeping it simple this is where I started.
FYI: I use Arch(LTS) to test ideas and Deb(12) is my workhorse.

#!/bin/bash

try with

read -n 1 choice

-n Returns after reading the specified number of characters.

:~$ sh bin/bashMenu.sh
Select:
1. Projects
2. Documents
3. Music

Worked fine here, and even the read command is working as intended on the command line. Befuddled I am.

Version of Bash on my system, since I did not send it last time.
GNU bash, version 5.1.16(1)-release (x86_64-pc-linux-gnu)

@mcron my Debian 12 GNU bash, version 5.2.15(1)-release (x86_64-pc-linux-gnu)
I think my Arch is 5.1.016-4 minimal, where the scripts work! I was able to reproduce error on the current Zorin in a virtual machine.

Interesting issue. Not critical as it’s just me on my machine.

I do have some bash scripts I want to share with my folk here. So surprised when debian barfed on basic options.

I use neofetch to display my system config but it does NOT show bash version

Your comment about Zorin had me curious so I tested your script successfully in a Zorin 16.3 VM. Might there be something in your $ENV which is somehow getting in the way?

@Narcosis Thanks for looking at this.
 I'll check the $ENV

I'm getting to know bash. Very interesting to learn how it works with aliases and custom prompts.

I'm sure I'll figure it out and will post what I find.
