7zr

Create and extract 7z archives

TLDR

[a]rchive a file or directory

$ 7zr a [path/to/archive.7z] [path/to/file_or_directory]

Encrypt an existing archive (including file names)

$ 7zr a [path/to/encrypted.7z] -p[password] -mhe=[on] [path/to/archive.7z]

E[x]tract an archive preserving the original directory structure

$ 7zr x [path/to/archive.7z]

E[x]tract an archive to a specific directory

$ 7zr x [path/to/archive.7z] -o[path/to/output]

E[x]tract an archive to stdout

$ 7zr x [path/to/archive.7z] -so

[l]ist the contents of an archive

$ 7zr l [path/to/archive.7z]

Set the level of compression (higher means more compression, but slower)

$ 7zr a [path/to/archive.7z] -mx=[0|1|3|5|7|9] [path/to/file_or_directory]

DESCRIPTION

The 7zr command is a lightweight, standalone version of 7-Zip designed for systems with limited resources or when only basic archive functionalities are required. It supports a subset of the 7-Zip archive formats, primarily 7z, zip, gzip, bzip2, xz, and tar. 7zr allows users to create, extract, and list the contents of archives.
Unlike the full 7-Zip package, it typically includes only the command-line executable and necessary codecs, reducing its footprint. This makes it suitable for embedded systems, recovery environments, and situations where a minimal archiving solution is preferred. 7zr excels in scripting scenarios, offering a straightforward command-line interface for automated archive management.

CAVEATS

7zr supports a reduced set of features compared to the full 7-Zip application. Some advanced compression methods or archive formats might not be available.

EXAMPLES

Create a 7z archive: 7zr a archive.7z files*
Extract a 7z archive: 7zr x archive.7z
List contents of a 7z archive: 7zr l archive.7z

HISTORY

7zr was created as a lightweight alternative to the full 7-Zip package, focusing on providing essential archiving functionalities in a smaller and more portable format. It is particularly useful in environments where disk space or system resources are limited, or when a simple command-line interface is sufficient. It has seen usage in rescue disks, embedded systems, and automated scripting environments. Development continues to maintain compatibility with common archive formats and provide a stable archiving solution.
