This question already has an answer here:
While reading through a bash style guide I found the following guideline:
Math / Integer Manipulation
a=5 b=4 # wrong if [[ $a -gt $b ]]; then ... fi # right if ((a > b)); then ... fi
When I inquired about the reasoning I was told that the
[[ test could potentially choke trying to compare numbers with leading zeros. In my testing I have not been able to recreate this issue.
Is there actually a functional difference between
((a > b))and
[[ "$a" -gt "$b" ]]?
