compare catalog and compressed catalog (is there new changes)


I want to compare catalog with compressed without extracting or compress files and compare. Is there any way to compare directory with compressed directory ?

Example: I have some files in tmpfs (ramdisk), before server shutdown, I need to save files to disk. In my opinion best way is compress files and save to disk like a file. On start server (system) I want to decompress files in to the ramdisk. But after couple days ramdisk files will be updated (different with compress file backup).

How to compare and merge diff ?

Solution

  • Executing:

    tar -tvf foo.tar.gz
    

    will show the contents of the compressed file without decompressing. You can then compare the files.
