I quite like mercurial .hgignore-style pattern globbing.
Globs are rooted at the current directory; a glob such as *.c will only match files in the current directory ending with .c.
The supported glob syntax extensions are ** to match any string across path separators and {a,b} to mean "a or b".
Is there a Linux shell that supports this?
All shells will support the standard glob *.c. KSH, Bash, and ZSH support brace expansion ({a,b}), but note that this not a file glob, so it will always expand. ZSH's extended globbing and Bash's globstar (bash v4 or higher), support ** for recursive globbing.
csh, ** comes from zsh (1991) and is now supported by ksh93 and tcsh. Also with bash and fish but with the caveat that they follow symlinks when recursing. zsh and tcsh have *** to follow symlinks. ** in ksh93 without the expected results. Does it require enabling a feature like globstar in bash? zsh. set -G in ksh93. bash got it from ksh93 as most things. See also that answer globstar. It is especially the recursive ** that I am after. shopt -s nullglob as well to avoid getting literally *.c if there is no file match.
.hgignoreignore patterns — they're not rooted for example. The section is about the general pattern supported by all commands. You use them likehg add "set:**.c", which works even when your shell doesn't (e.g., on Windows).
