I’ve always wanted to collect some useful git commands that I sometime use during my daily activity. Here are some that, from time to time, I go back to.
- Find the commit that added a line/a block in a file (warning: the line as of today):
git log -L start_line,finish_line:filename --format=%an | head -n 1
- Show old version of a file, given its commit hash (SHA):
git show <version>:<filename>
- Show number of lines modified per each developer in a file:
git blame --line-porcelain <filename> | sed -n 's/^author //p' | sort | uniq -c
| sort -rn
- Follow a file in git, if it was moved from another folder:
git log --follow -p <filename>
-p can be removed as it shows also the diff
- Full history of a file, even if it has been deleted:
git log --full-history -- <filename>
In case the path has been changed, git log --diff-filter=D --summary | grep <filename>
