  e=1  
    if [[ e -eq "1" ]]
            then
            echo "1"
            e=2
    fi

    if [[ e -eq "2" ]]
        then
        echo "2"
        e=1
    fi

Hi, I am trying to do this simple program in bash, but I have this error:

scriptCTH_v2.sh: 109: scriptCTH_v2.sh: [[: not found

Can you help me please?

How are you calling the script? You need to be explicitly using `bash`, not `sh` or another shell – arco444 Jul 31 '15 at 09:01
I am calling this program writing "sh scriptCTH_v2.sh" – flat1991 Jul 31 '15 at 09:02
Call it with `bash scriptCTH_v2.sh` and it should work – arco444 Jul 31 '15 at 09:03
I guess that you also want to be comparing `$e -eq 1`, rather than `e`. – Tom Fenech Jul 31 '15 at 09:08
Yes, it works! How it's possible? I'd like to understand! – flat1991 Jul 31 '15 at 09:09
I've added to the answer in the linked question - hopefully that makes things clear. – Tom Fenech Jul 31 '15 at 09:26
