Show all ignored files in git

Question

I'm having problems with git ls-files --others --ignored --exclude-standard not listing some ignored files.

My project has this directory structure

.
├── aspnet
│   ├── .gitignore
│   ├── __init__.py
│   ├── lib
│   │   ├── <lots of big stuff>

The aspnet/.gitignore lists lib/*, and git add aspnet/lib/foo reports that this path is ignored.

But git ls-files --others --ignored --exclude-standard does not list the files under lib. These are untracked files, they show up in output if I do git ls-files --others, but not if I provide the ignored flag.

Using git version 1.7.9.5

Edit: works as expected with git version 1.8.5.2 (Apple Git-48), this seems to be a git bug

Having find (likely on UNIX/Linux), you can issue the following command in the root folder of your git repository:

find . -type f  | git check-ignore --stdin

find . -type f will list all files in the folder recursively, while git check-ignore will list those files from the list, which are effectively ignored by .gitignore.

---

The check-ignore command is relatively new. If your .git version does not support it already, you can use the following workaround with a POSIX compatible shell (like bash, sh, dash, zsh). It is based on the fact that .gitignore contains glob patterns which are meant to be interpreted by a shell. The workaround iterates over the glob patterns from .gitignore, expands them in the shell and filters out directories from it:

while read glob ; do
    if [ -d "$glob" ] ; then
        # Be aware of the fact that even out of an ignored 
        # folder a file could have been added using git add -f 
        find "$glob" -type f -exec \
            bash -c "FILE={};[ \$(git status -s \$FILE) == "" ] && echo \$FILE" \;
    else
        for file in "$glob" ; do
            # Again, be aware of files which add been added using -f
            bash -c "FILE={};[ \$(git status -s \$FILE) == "" ] && echo \$FILE" \;
        done
    fi
# Pipe stderr to /dev/null since .gitignore might contain entries for non 
# existing files which would trigger an error message when passing them to find
done < .gitignore 2>/dev/null | sort

Doing this in a Windows PowerShell windows is straightforward:

PS> Get-ChildItem -Recurse | Select-Object Fullname | git check-ignore --stdin -v

The output does look kinda funky, as if it's designed for Cygwin or bash - which I don't use - so this may be my own misconfiguration, but it's still really helpful for finding out why that file is being ignored.

My Kung-Fu to list all ignored files recursively with rules

find . -type d | grep -v .git | awk '{print $1"/"}' | git check-ignore -v --stdin
