Check cached and Ignore files

git ls-files // List all cached files 
git ls-files | grep "env" // Check 'env' on cached files 
git ls-files --other --exclude=*.env --ignored // Check whther 'env' file is ignored 

Ignore files locally

Different methods to ignore files -

Method 1:

Edit file .git/info/exclude

Method 2

  git rm --cached <files>

Method 3

  git update-index --assume-unchanged path/to/file.txt
  
  git update-index --no-assume-unchanged path/to/file.txt (revert)

Bad Index issue

rm -f .git/index
git reset

Git clean

git clean -df // removed untracked directory (d) and untracked files (f)
