Find Out Author Of A Line With Git Log Or Git Blame

usecase

The concern is documenting the ways to find who is behind a particular change with git — not file history, but (as I call it) the line history.

1. git log -S

• one way of going about that
• you need a string or a piece of code
• you search the entire repo

git log -S "_STRING_" --pretty=format:"%C(auto)%h%d%Creset %C(cyan)(%ci)%Creset %C(green)%cn <%ce>%Creset" --name-status --date=short

1.1. example

git log -S "nomad" --pretty=format:"%C(auto)%h%d%Creset %C(cyan)(%ci)%Creset %C(green)%cn <%ce>%Creset" --name-status --date=short

2. git blame

• get the exact location within the file (exact line, or range, or the whole file if short)
• search within a single file
• you need a line number + filename
• run git blame with L parameter to see who has modified that line exactly

git blame -e -L _LINE_N_START_, _LINE_N_END_ _FILENAME_

2.1. example

git blame -e -L 9,9 C:\Users\Admin\Documents\workspace\work.log\kb\powershell\pub-wlog.ps1
