Usage
The following section describes various ways of usage of 7-zip.
Compressing and Uncompressing a Directory
For directories to be compressed the Lempel–Ziv–Markov chain algorithm is recommended. It is fast with good compression results.
As explained by
kenorb on superuser.com
An effective way to compress a directory is the following command where directory is the directory
that is to be compressed.
The archive will be created by the same name as the directory but with the .7z extension.
This command uses expansion.
The directory is not deleted automatically afterwards.
7z a -t7z -m0=lzma -mx=9 -mfb=64 -md=32m -ms=on directory{.7z,}
To uncompress it run the following command.
7z x directory.7z
Peek Contents of an Archive
To list the content files of a 7-zip archive the following command can be used.
The name of the archive is assumed to be directory.7z.
7z l directory.7z
Remove a File from an Existing Archive
To remove a file with the assumed name file.ext from an archive called directory.7z run the
following command as explained by

7z d -r directory.7z file.ext
