What compression tools are available in Ubuntu that can benefit from a multi-core CPU.
Recently, I've been backing up a lot of my data, and I noticed that I can save files as .gz or .tar.gz, or .7z and .tar.7z, etcetera. What are the differences between the normal one and the .tar.* variant? Which one of them is adviced when making backups?
I have a 72.9MB PDF file that I need to shrink into under 500KB.
The file was a JPEG image that I had scanned, and then converted to pdf.
I just realized I can't unrar .rar files on my Ubuntu machine!
What's the easiest way to accomplish this fundamental task? If possible I'd love something like 7Zip that I can just right Click, and extract and have the program worry about how to do it regardless if it's a .zip, a .rar or a .foo compressed file.
I'm trying to compress a directory and ftp it to a windows ftp.
I have tried every tar command I can find to compress a directory. It appears to be ok. Then I transfer it and view it's contents using Winrar. Winrar keeps telling me the file is corrupted. I have viewed other .gz or .bz2 files using winrar but for some odd reason I can't get it to work.
I would prefer just to have it zip the files so they have a .zip extension but even then when i try to browse it's contents both windows and winrar claim it's corrupt.
Does anyone else have a suggestion as to something else to try?
