Hi, I found the single-bracket [ ... ] and double-bracket [[ ... ]] behave differently for string comparison in the follow simple Bash-script. # comma (,) is before two (2) in ASCII a=,rst b=2rst if [ "$a" \> "$b" ]; then echo "single-bracket" fi if [[ "$a" > "$b" ]]; then echo "double-bracket" fi According to some web pages I was expecting that single-bracket and double-bracket should give same result. I'm not a Bash-expert, therefore I'm not sure whether this is a real bug in Bash 5.0. Merry Christmas! Xin PS: the web pages are: * http://tldp.org/LDP/abs/html/comparison-ops.html * http://tldp.org/LDP/abs/html/refcards.html * http://mywiki.wooledge.org/BashFAQ/031
