Solution

7za — File archiver with a high compression ratio. Similar to 7z except that it supports fewer file types but is cross-platform. More information: <https://manned.org/7za>.

[a]rchive a file or directory:

7za a {{path/to/archive.7z}} {{path/to/file_or_directory}}

Encrypt an existing archive (including file names):

7za a {{path/to/encrypted.7z}} -p{{password}} -mhe={{on}} {{path/to/archive.7z}}

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

7za x {{path/to/archive.7z}}

E[x]tract an archive to a specific directory:

7za x {{path/to/archive.7z}} -o{{path/to/output}}

E[x]tract an archive to stdout:

7za x {{path/to/archive.7z}} -so

[a]rchive using a specific archive type:

7za a -t{{7z|bzip2|gzip|lzip|tar|...}} {{path/to/archive.7z}} {{path/to/file_or_directory}}

[l]ist the contents of an archive:

7za l {{path/to/archive.7z}}

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

7za a {{path/to/archive.7z}} -mx={{0|1|3|5|7|9}} {{path/to/file_or_directory}}
