/usr/bin/select shell script menu TC 4.6.1 and TC 5.2

(1/2) > >>

KHarvey:
I'm attempting to write a shell script that prompts the user to select from a menu of choices.  But I am unable to get the select statement to work.  I keep receiving an error

--- Code: ---/usr/bin/select:  line xx: can't open in: no such file

--- End code ---
xx in TC 4.6.1 is 54
xx in TC 5.2 is 62

I attempted to just use a basic script to make sure that it wasn't my convoluted code:

--- Code: ---#!/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

--- End code ---
But even that code fails with the same error.

I can probably write the same thing using if statements and accomplish the same thing.  But I figured I would ask anyways.
Please note I have not tried any of this code on another distro, I have only tried it on TC.

bash is /usr/local/bin/bash, not /bin/bash.

KHarvey:
Gah!
I was actually using /bin/sh for my script.  The example that I posted above was copied and pasted from the website that I was using to test.
But if I use /usr/local/bin/bash then the script runs properly.  I have a lot of scripts that I need to go change from /bin/sh to /usr/local/bin/bash.

Thanks for pointing out my error.

Hi KHarvey,

You may not need to change all your scripts.

Although I have  limited knowledge about the differences of shells, I believe it is because you wanted to use an array that you need to use the bash shell.

AFAIK sh does not support arrays directly.

That sounds like really bad practice in two aspects:

1. Never ever use a bash header for portable shell scripts without explicit bashisms.

2. Never ever use #!/usr/local/bin/bash as header for bash scripts, but always #!/usr/bin/env bash.
