[1] and macOS (from FreeBSD[1]) says the exact opposite : -h file True if file exists and is a symbolic link. This operator is retained for compatibility with previous versions of this program. Do not rely on its existence; use -L instead. agree it would be a good idea to use only one for consistency though, but it might be in that case a good idea to add it as a "recommendation" by adding this rule in t/check-non-portable-shell.pl or something like that IMHO Carlo [1] https://www.freebsd.org/cgi/man.cgi?test
