Find and search inside encrypted compressed files

Question

I want to get a list of all contents inside a (ZipCrypto) password protected zip archive inside the terminal.

Also, how can I filter/search specific file types using grep (Can I)?

Answer 1

You can encrypt files, but still leave the file list unencrypted. If thats the case, save the following code, as finda.sh, or any other name as you like:

for file in *.*; do
    if ( 7z l -slt "$file"> /tmp/$file.log); then
       echo $file:; cat /tmp/$file.log | grep -iE 'Path*'> $file.log && cat $file.log
    fi
done

Save funda.sh In a directory were all of your archives are in, then execute it, and this is the output:

./finda.sh 
one.7z:
Path = one/abradabra.png
Path = one/birb.png
three.rar:
Path = three/blah.png
Path = three/qwa0g.jpg
two.zip:
Path = two/whut.png

Answer 2

I don't think you can do this with encrypted compressed file.

But you can search for compressed files with no password using zgrep

 zgrep 'word-to-search' /path/to/test.gz

man zgrep

Zgrep invokes grep on compressed or gzipped files. All options speci‐ fied are passed directly to grep.
