Right. I stand corrected. Thanks. Do you have an opinion on whether POSIX should allow the expansion of globs not to include "." and ".." by default? Today, one generally doesn't want for "." and ".." to be included in the expansion, but on the odd chance that one does, set -- .* is not guaranted to have "$@" include them. $ bash -c 'echo .*' . .. .git $ dash -c 'echo .*' . .. .git $ ksh93 -c 'echo .*' . .. .git $ mksh -c 'echo .*' .git $ posh -c 'echo .*' .git $ zsh -c 'echo .*' .git $ (exec -a sh zsh -c 'echo .*') .git -- Stephane
