How to roll back Git Commit in salesforce?

Hi Vikas,

Reverting Working Copy to Most Recent Commit
To revert to a previous commit, ignoring any changes:

git reset --hard HEAD

where HEAD is the last commit in your current branch

Reverting The Working Copy to an Older Commit
To revert to a commit that's older than the most recent commit:

# Resets index to former commit; replace '56e05fced' with your commit code
git reset 56e05fced

# Moves pointer back to previous HEAD
git reset --soft HEAD@{1}

git commit -m "Revert to 56e05fced"

# Updates working copy to reflect the new commit
git reset --hard
