I've read several questions on this forum on how to do this but cannot find a way to do this via p7zip. I want to basically have p7zip go through a a directory and turn each top level directory in that directory into a zip or 7zip file. So for example I cd to directory a. I want directory b, c, d, e, etc to turn into their respective compressed files. I'm not an advanced user with the command line. I will get there, so bare with me in asking this question. p7zip by the way is a compression utility that does rar, zip and more through a command line interface.

On Linux/Unix you still have to use tar in order to backup directories. p7zip is still just a file compressor:

tar cf - [directory a] | 7z a -si [filename].tar.7z

  • Actually it is not. I can do on m mac 7z a filename.7z path/to/directory. For example dropbox.com/s/wakwcxpz7t8xpg6/… I've done this on a linux machine running p7zip as well.

  • That's pretty special then since this is straight from from the p7zip documentation from the author:

  • On Linux/Unix, in order to backup directories you must use tar ! to backup a directory : tar cf - directory | 7za a -si directory.tar.7z to restore your backup : 7za x -so directory.tar.7z | tar xf -

  • The author specifically warns against using the -r flag to recurse directories if you're making backups because it will not get all that hidden files and directories that begin with a dot. He specifically says you need to use tar.

  • I never wanted to back up directories. I'm zipping them or in this case trying to run a batch compression to make uploading easier, or in some user's case downloading. So there must be away. As shown I did do this in my example. I did 7zip a directory, or in this case archive a directory using p7zip.
