rredtool - Man Page

merge or apply a very restricted subset of ed patches


rredtool --help

rredtool [ options ] --merge patches...

rredtool [ options ] --patch file-to-patch patches...

rredtool directory newfile oldfile mode


rredtool is a tool to handle a subset of ed patches in a safe way. It is especially targeted at ed patches as used in Packages.diff and Sources.diff. Is also has a mode supposed to be called from reprepro as Index Hook to generate and update a Packages.diff/Index file.


One of the following has to be given, so that rredtool know that to do.


Print the version of this tool (or rather the version of reprepro which it is coming with).


Print a short overview of the modi.


The first argument of rredtool is the file to patch, the other arguments are ed patches to apply on this one.


The arguments are treated as ed patches, which are merged into a single one.

--reprepro-hook (or no other mode flag)

Act as reprepro index hook to manage a Packages.diff/index file. That means it expects to get exactly 4 arguments and writes the names of files to place into filedescriptor 3.

If neither --patch nor --merge is given, this mode is used, so you can just put

DebIndices: Packages Release . .gz /usr/bin/rredtool

into reprepro's conf/distributions file to have a Packages.diff directory generated. (Note that you have to generate an uncompressed file (the single dot). You will need to have patch, gzip and gunzip available in your path.)



Print intermediate results or other details that might be interesting when trying to track down bugs in rredtool but not intresting otherwise.


When generating a Packages.diff/Index file, put at most count patches in it (not counting possible apt workaround patches).


Not yet implemented.



temporary files are created in $TEMPDIR if set, otherwise in $TMPDIR if set, otherwise in /tmp/.
