gitdiff

Git diff to show only lines that have been modified

When I do a git diff, it shows lines that have been added:

+ this line is added

lines that have been removed:

- this line is removed

but it also shows many lines which are not modified:

this line is not modified
this line is also not modified

This results in the actual git diff looking something like this:

+ this line is added
  this line is not modified
- this line is removed
  this line is not modified

Can I ask git to show only lines that have been modified and ignore all other code which has not been modified? I have written a method which will remove all the lines which don't have a "+" or "-" sign in front of them, but I am sure there must be a simpler way to do this.

In my git diff, I am only interested in seeing the lines that have been modified.

Solution

  • What you want is a diff with 0 lines of context. You can generate this with:

    git diff --unified=0

    or

    git diff -U0

    You can also set this as a config option for that repository:

    git config diff.context 0

    To have it set globally, for any repository:

    git config --global diff.context 0
