XK0-005 Question #1233: Real Exam Question with Answer & Explanation

Question

A Linux administrator needs to add some files in a directory to the Git repository but must exclude some local .tmp files that are occasionally created by the scripts. Which of the following is the BEST way to accomplish this task?

Options

• Agit rm .tmp
• Bgit add -x .tmp *
• Cecho .tmp >> .gitignore
• Drm -rf .tmp

Explanation

To prevent Git from tracking specific local files like temporary files, add their patterns to the .gitignore file.

Common mistakes.

• A. git rm .tmp would remove the file .tmp from the Git repository if it was already tracked, but it does not prevent future untracked .tmp files from being listed by Git.
• B. git add -x .tmp * uses an invalid flag -x for git add; git add is used to stage files for commit, not to exclude them.
• D. rm -rf .tmp deletes the .tmp file from the filesystem but does not configure Git to ignore similar files in the future.
