git annotate

Show commit hash and last author on each line of a file. See git blame, which is preferred over git annotate. git annotate is provided for those familiar with other version control systems. More information: https://git-scm.com/docs/git-annotate.

• Print a file with the author name and commit hash prepended to each line:

git annotate path/to/file

• Print a file with the author email and commit hash prepended to each line:

git annotate -e|--show-email path/to/file

• Print only rows that match a regular expression:

git annotate -L :regexp path/to/file
