Hi. I noticed a (to me) unexpected difference between bash and dash, compare bash behaviour: jas@latte:~$ mkdir -p foo foo/bar jas@latte:~$ cd foo/bar jas@latte:~/foo/bar$ command -v ../bar jas@latte:~/foo/bar$ echo $? 1 jas@latte:~/foo/bar$ with dash behaviour: $ mkdir -p foo foo/bar $ cd foo/bar $ command -v ../bar ../bar $ echo $? 0 $ That is, dash's 'command -v' return success on directories for relative names. I believe the dash behaviour is incorrect, but I'd appreciate if someone else read the POSIX spec here. Do you agree? This is on Debian bullseye with dash 0.5.11+git20200708+dd9ef66-5 and bash 5.1-2+deb11u1. /Simon
