splitpatch(1) split a patch up into files or hunks


splitpatch [options]


Divide a patch or diff file into pieces. The split can made by file or by hunk basis. This makes is possible to separate changes that might not be desirable, or assemble a patch into more coherent set of changes.

The hunk option makes it possible to compare similar patches on a hunk-by-hunk basis using a tool like interdiff(1) from the patchutils package.


-H, --hunk, --hunks
Split patch by hunks instead of the default: by file.
-h, --help
Display help and exit
-V, --version
Output version information and exit.


Have you ever been working on code, gone off on a side tangent and then realized you don't have a patch for the original issue you set out to address? When you run "diff -u" or some other diff command, you discover that you have made multiple sets of changes; some you want to submit, others you don't. What you really want to do is break those changes apart and apply only the ones you want. This is where splitpatch comes into play, breaking up the patch by source file:

    splitpatch changes.patch

Or to split the patch file into individual hunks which can later be applied using the patch(1) command:

    splitpatch --hunks changes.patch




The --hunk option writes sequentially numbered files in the current directory named for the source file to be patched followed by the sequence number: "*-NNN.patch".

Otherwise, the split patch files are named by the source file being patched.
