Quoting and string comparison

[Jaan Vajakas]

Hi!

I noticed a weird behavior. Is it a bug?

Namely, why does

echo "$(for f in a b c; do if [[ \"$f\" > b ]]; then echo "$f > b"; else
echo "$f <= b"; fi; done)"

output

a <= b
b > b
c > b

?

I would have expected the same output as one of
echo "$(for f in a b c; do if [[ "$f" > b ]]; then echo "$f > b"; else echo
"$f <= b"; fi; done)"
echo "$(for f in a b c; do if [[ '"$f"' > b ]]; then echo "$f > b"; else
echo "$f <= b"; fi; done)"

This happens e.g. on GNU Bash v4.4 (e.g.
https://www.tutorialspoint.com/execute_bash_online.php ).


Best regards,
