How to Run on Mac?

[xigwon]

Hello, I am sort of new to using Terminal. How do I get this running on my Mac? I tried "fix-onedrive-zip [filename]" and it said "command not found".

Hey @xigwon

To run the fix-onedrive-zip script, you need to have perl installed on you system. Run perl -v in your terminal window to check. You should get something like this

$ perl -v

This is perl 5, version 32, subversion 1 (v5.32.1) built for x86_64-linux-gnu-thread-multi
(with 47 registered patches, see perl -V for more detail)

this system using "man perl" or "perldoc perl".  If you have access to the
Internet, point your browser at http://www.perl.org/, the Perl Home Page.

If that didn't work you need to install perl.

Assuming you do have perl installed, try running perl fix-onedrive-zip yourzipfile.zip

Thank you @pmqs , I have perl (5.18.4) installed, but when I tried perl fix-onedrive-zip zipfilename.zip it said "Can't open perl script "fix-onedrive-zip": No such file or directory". Do you know how to fix this? Thanks again.

Hey @xigwon

I'll keep this as simple as possible

1. before you start, make sure that the fix-onedrive-zip script and the zip file you want fixed are in the same folder. Let's say it is /Users/xigwon/zip. I don't have a Mac, but I believe Finder is the application for to use.
2. then in the terminal window run cd /Users/xigwon/zip (replace the path with the location you have actually used)
3. now try running perl fix-onedrive-zip yourzipfile.zip

Hi @pmqs! So glad I found this, I signed up to GitHub :) Needless to say i'm nothing of a coder. So I have another question regarding execution of the script on mac : I think I did everything right, downloaded the script, saved it in the same folder as my zip file, made sure I have perl installed, selected the right folder in the console, ran the script and got the error "Error: bad offset 0x3A19A19 at end of 'OneDrive_H.zip'". Is my file beyond hope? Thanks :)

Hi @hanae-ngn

the error you are getting suggests that you don't have a OneDrive zip file with the error that my script is designed to fix, but it could be a variation on a OneDrive zip file that I haven't seen before.

Can you show the output you get when you try to unzip OneDrive_H.zip? I need to see what the error message you are getting.

To check this further, could you run zipdetails against the file & include the results. This will output all the metadata present in the zip file and give me a clearer picture about the internal structure of your zip file.

Usage is

perl zipdetails -v --redact OneDrive_H.zip

The redact option will obscure the filenames output, if that is a concern for you.

The zipdetails script has the potential to output a LOT of data. If that is the case and there is too much data to upload, I only really need to see the end of the output. Something like this should get enough for my purposes.

perl zipdetails -v --redact OneDrive_H.zip | tail -n 100

FYI, this is is an example section at the end of the zipdetails output that I want to see.

Thanks so much for your reply and details @pmqs! The message I get when I try to extract the file is "Cannot open file 'OneDrive_H.zip'. It does not appear to be a valid archive." (screenshot included)

When I run perl zipdetails -v --redact OneDrive_H.zip, I get a very small output which kinda worries me.

Should mention that this is a file I downloaded and saved on a GDrive from one Mac, then downloaded from GDrive on another Mac, I feel that has potential to mess things up?

@hanae-ngn

try running zipdetails with the --scan option. Note that it may take a long time to run

perl zipdetails -v --redact --scan OneDrive_H.zip
