UNIX for Dummies Questions & Answers

Hi Guys,

We have some really large zip files containing hundreds of files, we need to search within these compressed files for a string in the filename eg ABC if found then extract the file from the zip ?

I've searched for a long time but no joy

Any help really appreciated

Thanks

Pete

Hi, have you checked out zipinfo and zipgrep?

Hi

Yeah I have checked them out but can't see a way to search lots of zip files within a directory and only extract if a match is found on part of the filename within the zip.

Cheers

OK, how about:

Code:

unzip "*.zip" "*ABC*"

This should extract every file whose name contains "ABC" from every zip archive in the current directory

Won't this have to extract the data in order to find the files ? The problem is the machine is our main database server and I cannot risk uncompressing loads of files and filling up the disk. I have tried the following find command

find . -name '*.zip' -exec grep -qi '*ABC*' {} \; -exec echo {} \;

This finds and lists the files but how do I then tell unzip to only the unzip files it found the file in and not to unzip everthing just to extract files containing ABC in the filename.

Cheers

The command I posted should only extract the files that match the pattern. I just did a test to verify and I think that is what happened.

Code:

$ unzip "*.zip" "*g*"
Archive:  testzipper.zip
replace dfgdhdgfdreggegerg? [y]es, [n]o, [A]ll, [N]one, [r]ename: A
 extracting: dfgdhdgfdreggegerg

Archive:  testz2.zip
 extracting: dfgdhdgfdreggegerg

2 archives were successfully processed.

But it is never a good idea to test something on a production server. Why don't you copy one or two of those zip files onto a test server and test it yourself so you can be sure.

Yes I have copied some of the files to a test machine and confirmed that I did only need to do unzip "*.zip" "*ABC*" which worked great

Thanks for your help

cheers
