ytdiff

Yet-another Tar-Diff tool.

It mounts (or expands) two tar files in a temporary directory, then compares the directories with diff command, and finally remove the temporary directory.

Usage

ytdiff: Diff between two .tar files.
Recognized tar file extensions are: : .tar, .tgz, .tar.gz, .tar.bz2, .tbz, .tbz2, .tar.xz, .tar.lzma, .tlz, .tar.Z

Usage:
  ytdiff -r <options>... <tar1> <tar2>
  ytdiff --git <options>... <tar1> <tar2>
  ytdiff <options>... <gzip1> <gzip2>

Options:
  --git     Use `git diff` instead of `diff`.
  -r        Recursive option, passed through to diff command.

All the other options will be passed through to `diff` command.

Mini tutorial

Let make two directories to be compared as follows:

$ rm -rf d
$ mkdir d
$ echo A > d/A.txt
$ echo B B > d/B.txt
$ tar zcvf d-1.tar.gz d/*
d/A.txt
d/B.txt
$ echo B C > d/B.txt
$ tar zcvf d-2.tar.gz d/*
d/A.txt
d/B.txt

Compare the two directories.

$ ytdiff -r d-1.tar.gz d-2.tar.gz
diff -r a/d/B.txt b/d/B.txt
1c1
< B B
---
> B C

Compare them with git diff command, instead of diff command.

$ ytdiff --git --word-diff d-1.tar.gz d-2.tar.gz
diff --git a/a/d/B.txt b/b/d/B.txt
index 1090f0c..a12ea8a 100644
--- a/a/d/B.txt
+++ b/b/d/B.txt
@@ -1 +1 @@
B [-B-]{+C+}
