How do I run git bisect only on commits that changed a certain file? [duplicate]

Question

I have a bug that have been introduced a long time ago, and testing for it is painful. However, I strongly suspect that changes which introduced the bug happened in one particular source code file.

Can I run git bisect on a sub-set of commits that changed that one file?

Answer 1

Yes, you can. In the manpage, you find this line:

git bisect start [--term-{old,good}=<term> --term-{new,bad}=<term>]
      [--no-checkout] [<bad> [<good>...]] [--] [<paths>...]

so after --, you put the paths of the files or directories.

For example:

git bisect start -- arch/i386 include/asm-i386
