.gitignore is ignored by Git

Question

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?

Answer 1

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"
