My .gitignore file seems to be being ignored by Git - could the .gitignore file be corrupt? Which file format, locale or culture does Git expect?

My .gitignore:

# This is a comment
debug.log
nbproject/

Output from git status:

# On branch master
# Your branch is ahead of 'origin/master' by 1 commit.
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       debug.log
#       nbproject/
nothing added to commit but untracked files present (use "git add" to track)

I would like debug.log and nbproject/ not to appear in the untracked files list.

Where should I start looking to fix this?

Even if you haven't tracked the files so far, Git seems to be able to "know" about them even after you add them to .gitignore.

WARNING: First commit or stash your current changes, or you will lose them.

Then run the following commands from the top folder of your Git repository:

git rm -r --cached .
git add .
git commit -m "fixed untracked files"
