How to ignore files for being tracked in Git ?

Create a file with name .gitignore

$ cat .gitignore

Provide the patterns of files that you don’t want to automatically add or show as untracked.

Example

# ignore .txt files
*.txt

# but do track hello.txt, even ignoring .txt files above
!hello.txt

# ignore all files in the build/ directory
build/



# ignore the README file in the current directory, not subdir/README
/README

# ignore all PPT files in doc directory, but not PPT files under doc/subdir/
doc/*.ppt

# ignore all .txt files in the doc directory and its subdir
doc/**/*.txt
