New page

I had a very large number of encrypted zip files created using 7zip. These needed to be decrypted so I wrote out the following script to run while I did more important things.<br>
The key is that you know the file structure inside your archives. For me this was
#Directory holding the zipped files
#The encrypted zipped files
#Sub directory inside encrypted zipped files
#The files
I needed to recreate this structure in an un-encrypted form so this would be a nested looping script. The only "issue" is that the script outputs the directories with the .zip extension. I was just too lazy to remove it from the directory name but would be an easy addition to the script.

<pre>
#!/bin/bash
ls -1 /source/directory > /tmp/filelist1
while read line
do
ls -1 /source/directory/$line > /tmp/foundzip
while read line2
do
mkdir -p /destination/directory/$line/$line2
7za x -ppassword /source/directory/$line/$line2 -o/destination/directory/$line/$line2
done < /tmp/foundzip
done < /tmp/filelist1
rm -f /tmp/foundzip
rm -f /tmp/filelist1
</pre>
