查找删除两个修订之间的界线的提交

Question

I am trying to find the commit that deleted a line between between two revisions. I could not find it directly.

This is what I tried in the following:

git blame $v1..$v2 -L $line,+1 --reverse -- $file_name

then this command line returns the line that was deleted and not the commit in question. I searching for this character string using these methods:

1- Search in commits that have modified the function where the line is.

git show $commit:$file | grep -Fq "$st"

2- Searching using the character string.

git log $v1...$v2 --pretty=format:"%h"  -S"$String" $file

In the first, I could not find the function containing that line (or it doesn't exist) in some cases. In the second approach, The string could be repeated in several cases and I need to review all of them.

I need a better way to find the commit that deleted the line.

Answer 1

I usually use a pickaxe search

git log -SFoo -- path_containing_change 

That lists commits which introduced the string Foo, but also the commits where Foo was deleted .
Yes, with that approach you need to review those commits in order to determine which one add or remove Foo .
