bzip2 uncompress issue

[pnbalaji]

Hi,

I downloaded a zip file from one of our vendor portal and tried to unzip the file with Archive Manager and Xarchiver. However, I am getting the message "Skipping 1.txt. 'bzip2' method not supported'.

Can some one help? I have bzip2 installed already.

Thanks,
Balaji.

I think you are confused, or what you write is confusing. You're talking about a zip file and then you're talking about bzip2 compression. These are not the same thing. Not the same filetypes, not the same compression method either.

Hi,

Thanks for the response.

I know I mentioned about the zip because the file name is "INV_01XX.zip". However, when I try to extract the file Archive Manager complains that bzip2 is not supported. I am assuming that the vendor portal uses the bzip2 compression method to create the zip file instead of .bz2 file.

Let me know if it still confuses you.

Thanks,
Balaji.

Yes, it does. If it says ".zip", it's not a bzip2 compressed file, it is a zip compressed file.

And certainly engrampa, the archive manager we have as default in salix, can decompress both zip and bzip2 compressed files.

In a terminal try

Code: Select all

unzip -lv (whatever the file is called)

This should list the files (rather than actually extracting anything) and also give verbose output.

If it isn't actually a zip archive, it will say so. If you think it's bzip2, tar should do the job (I don't know if it cares whether the file you give it has the correct termination). Try:

Code: Select all

tar -xvf (filename)

which I think will unpack almost anything, and give verbose output. If it really is bzip2, the right switch is j I think:

Code: Select all

tar -xjvf (filename)

though again, it may want the filename to end in .bz2

This is largely from memory so if in doubt, please check the relevant man pages.

EDIT

Also, check the download isn't corrupted.

I tried to uncompress one file from the zip using xarchiver and this is what I am seeing.



I will try to re-download the file and see how it works.

Thanks,

What happens if you "extract" the file and then try and read it in a text editor? The .txt file may already be in an unzipped state.

[pnbalaji]

I am getting the above error messages even when I try to extract one single file from the archive.

Thanks,
Balaji.

What happens if you run:

Code: Select all

unzip INV_20130502121041.zip 

[pnbalaji]

This is what I am getting.

[bneelka@darkstar~/corp/salesforce]unzip INV_20130502121041.zip
Archive: INV_20130502121041.zip
skipping: 11265422.txt `bzip2' method not supported
skipping: 11265424.txt `bzip2' method not supported
skipping: 11265425.txt `bzip2' method not supported
skipping: 11730586.txt `bzip2' method not supported

I re-downloaded the file several times and I am getting the same error message every time. It doesn't work in windows also. So, at this point, I am assuming that this is a problem with the vendor portal and I sent an email to them just now. Thanks for every one who were trying to help.

I will keep you posted once I get response from the vendor.

Thanks,
Balaji.
