7-Zip
7-Zip is a file archiver with a high compression ratio.
Installation
The command to run the program is the following:
$ 7z
Examples
Warning: 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
:
Warning: 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 without using directory names:
$ 7z e archive_name
Extract with full paths:
$ 7z x archive_name
Extract into a new directory:
$ 7z x -ofolder_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.
