git log -L:function_name:file_name can be used to get the log of all commits that touched a specific function. But it always shows the content/diff of the commit as if -p option was applied.

Is there a way to search for a specific string introduced from a merge commit?

I asked git to show me all the commits that modified a certain file, and it produced what I asked, except some commits show no modification to said file (and so instead only the commit hash/author/message etc… appears). It seems that most of these commits are merges. What could be the meaning of this ?

While pushing my commits to the remote branch and after staging files with git add ., Git unexpectedly created a new file named h containing commit logs. I’m unsure why this happened since I hadn’t accidentally executed any Git commands, although I did run git log without parameters, which typically doesn’t create files.
