Find removed line is really useful.Because git blame can check who added this line, but there is no command to check who delete one line.

find_removed_line.sh can provide which commit deleted specific code content.

Usage of find_removed_line.sh:

cd $your_git_folder

./${path}/find_removed_line.sh "$removed_string"

For example:

cd vendor/mmm/aaa/

~/git_tools/find_removed_line.sh "Add zzz related change"

The output is:

      The line Add zzz related change is removed in commit: 1fa9bebd8b362c0afbb2186e3fe6ef085d8c0762

      commit 1fa9bebd8b362c0afbb2186e3fe6ef085d8c0762
