A parenthesised suffix on a zsh glob filters the matches. '*(.)' keeps only regular files, '*(/)' only directories, '*(@)' only symlinks, and '*(x)' only executables. Size and age predicates use 'L' and 'm', so '*(Lm+10)' matches files larger than ten megabytes and '*(mh-2)' files modified in the last two hours.

Ordering and slicing are qualifiers too. '*(om[1])' is the most recently modified entry and '*(.om[1,5])' the five newest regular files. 'D' includes dotfiles, 'N' makes an empty match silent, and they combine as '*(.DN)'.

This matters for correctness, not just brevity: 'rm *(.)' cannot accidentally recurse into a directory the way a bare 'rm -r *' can, and '*(om[1])' avoids the classic 'ls -t | head -1' pipeline that breaks on filenames containing newlines. The qualifiers are zsh-only; a script using them must have a zsh shebang, not sh.
