7-Zip is a file archiver with a high compression ratio. It was previously provided by the p7zip package.

Installation

Install the 7zip package.

The command to run the program is the following:

$ 7z

Alternatively, bsdtar(1) provides 7z archive support and is included within the libarchive package.

Examples

Do not use 7z format for backup purposes, because it does not save owner/group of files.

Add file/directory to the archive (or create a new one):

$ 7z a archive_name file_name

Also it is possible to set password with flag -p and hide structure of the archive with flag -mhe=on:

Using the -p flag will ask you to enter a password on the command line. As of version 24.09, what you provide at the Enter password: prompt is no longer hidden; what you type is visible, and no password confirmation is requested.

$ 7z a archive_name file_name -p -mhe=on

Update existing files in the archive or add new ones:

$ 7z u archive_name file_name

List the content of an archive:

$ 7z l archive_name

Extract all files from an archive to the current directory:

$ 7z x archive_name

Extract into a new directory:

$ 7z x -odirectory_name archive_name

Check integrity of the archive:

$ 7z t archive_name

Differences between 7z, 7za and 7zr binaries

The package includes three binaries:

  • 7z uses plugins to handle archives.

  • 7za is a stand-alone executable that handles fewer archive formats than 7z.

  • 7zr is a stand-alone executable. It is a "light-version" of 7za that only handles 7z archives. In contrast to 7za, it cannot handle encrypted archives.
