Is there a way to use shell globbing to identify nested directories?

so if I have dir/dir1/dir2/dir3/dir4/dir5/.. and I have files under all of them, what is the equival

    In Bash 4, with shopt -s globstar, and zsh you can use **/* which will include everything except hidden files. You can do shopt -s dotglob in Bash 4 or setopt dotglob in zsh to cause hidden files to be included.

    In ksh, set -o globstar enables it. I don't think there's a way to include dot files implicitly, but I think **/{.[^.],}* works.

    You may try:

    **/*.*
    

    However it'll ignore hidden files (such as .git files). Sometimes it's a life-saver.

    If you want to act on all the files returned by find, rather than just list them, you can pipe them to xargs:

    find <directory> -type f | xargs ls
    

    But this is only for commands that don't have a recursive flag.

    There is no way to do this with vanilla Bash, however most commands accept a -R or --recursive option to tell them to descend into directories.

    If you simply want to list all files located anywhere within a directory or its sub-directories, you can use find.

    To recursively find files (-type f) with a given directory:

    find <directory> -type f

    Specifically about git (gitignore, gitattributes, and commands that take filenames): if the pattern contains no slash, * wildcards will match deep. If it does contain a slash, git will call fnmatch with the FNM_PATHNAME flag, and simple wildcards won't match slashes. ** to match deep isn't supported. Maybe this kind of deep matching could be more widely supported with a new FNM_STARSTAR flag, and an implementation in glibc, gnulib and other places.

    You can use tree, it will show all folders recursively.

    tree <path>
