Reverting a file(s) to a specific Git commit

gistfile1.sh

# find the file w/path you want to revert
find <a-parent-directory-of-file> -name "<name-of-file>"

# get all commits (hashes) where changes were done to this specific file
git log --abbrev-commit --pretty=oneline <path-to-your-file>

# revert this file (while keeping changes in the history) to this hash
git checkout <hash> <path-to-your-file>

# do a 'git add' and 'git commit'

# view the commits on the file (all are still there, yours is the most recent)
git log --abbrev-commit --pretty=oneline <path-to-your-file>
