Does anyone have a good how to for using p7zip? I've been searching for about 20 minutes, and haven't found anything helpful. I installed it, and I have two binaries, 7z and 7za. What's the difference?? Does this software use the high compression algorithm (i dont know the name, but i know this software uses the highest compression algorithm) by default? Can I change the compression and speed settings like i can with bzip2 and gzip (eg. bzip2 -9)? I would really like to learn this software, and need to soon because I have to go to sleep and wake up soon to go to a Linux User Group meeting. Thanks for your replies.

I found this:
http://www.penguin-soft.com/penguin/man/1/7z.html

-mx=... option seems to set the compression ratio in the example. Maybe you can try that?

that is the same as the man page. do you know what the difference between /usr/bin/7za and /usr/bin/7z is?

Hi,

7za is a stand-alone executable. 7za handles less archive formats than 7z, but does not need any others.

And that is a qoute from the manpage

I'm closing this thread since its essentially the same as the one here.
