Im trying to code a small markdown to DocuWiki converter myself as BASH practice, somehow I'm getting Syntax errors while executing following Code:

#!/bin/bash
Heading1=($(grep -E '^\={5}\s.*\s\={5}$' ZimSyntax.txt))
VAR='====='
for i in ${Heading1[@]}; do
    if [ "${Heading1[i]}" != "${VAR}" ]
        then
            echo $i     
    fi
done

Error: ./converter.sh: line 21: =====: syntax error: operand expected (error token is "=====")

Sample Array Data:

===== 
Heading
1
=====
=====
Heading
1
=====

ZimSyntax.txt:

==== Heading 2 ====  
===== Heading 1 =====  ===== Heading 1.2 =====
===== Erhing 1 =====
===== Header 1 =====
===== whatever =====

Reachyy

Try pasting your code on https://www.shellcheck.net/ to check for common bash-errors. – 0stone0 May 21 '21 at 14:42
Could you please provide an example of `ZimSyntax.txt` ? – 0stone0 May 21 '21 at 14:43
You need spaces around `!=` – Barmar May 21 '21 at 15:47
Question is Edited, ZimSyntax example added, spaces around != did not change anything. – Reachyy May 22 '21 at 07:44
