Ubuntu Manpage: 7z - 7-Zip file archiver with a high compression ratio

SYNOPSIS

`7z`	command [switches...] archive_name [file_names] [@listfile]

7zz command [switches...] archive_name [file_names] [@listfile]

7za command [switches...] archive_name [file_names] [@listfile]

7zr command [switches...] archive_name [file_names] [@listfile]

DESCRIPTION

7-Zip file archiver with a high compression ratio
There are some variants for 7z executable.

7z: Full featured with plugin support
7zz: Full featured single binary executable with no plugins support
7za: Supports major formats only, no plugins, but smaller executable size
7zr: Only supports LZMA codec and related formats (7z, lzma, xz), no plugins, but smallest executable size

Important Note of 7zip behavior

When used without any file_names argument, 7z implicitly uses "." for file_names. This behavior leads some unexpected result.

"a" (add) command: Recurcevily add files from current directory into archive_name file.
"d" (delete) command: Recurcively delete files from archive_name file. This means delete all files from archive_name file.

OPTIONS

Commands

a: Add files to archive
b: Benchmark
d: Delete files from archive
e: Extract files from archive (without using directory names)
h: Calculate hash values for files
i: Show information about supported formats
l: List contents of archive
rn: Rename files in archive
t: Test integrity of archive
u: Update files to archive
x: eXtract files with full paths

Switches

--: Stop switches and @listfile parsing
-ai[r[-|0]]{@listfile|!wildcard}: Include archives
-ax[r[-|0]]{@listfile|!wildcard}: eXclude archives
-ao{a|s|t|u}: set Overwrite mode
-an: disable archive_name field
-bb[0-3]: set output log level
-bd: disable progress indicator
-bs{o|e|p}{0|1|2}: set output stream for output/error/progress line
-bt: show execution time statistics
-i[r[-|0]]{@listfile|!wildcard}: Include filenames
-m{Parameters}: set compression Method

-mmt[N]: set number of CPU threads
-mx[N]: set compression level: -mx1 (fastest) ... -mx9 (ultra)
-mcp=[codepage number]: [Extra options for Zip format]:
Use codepage number for file name encoding. When 7-Zip detects legacy Zip format, 7-Zip automatically choose suitable legacy codepage number by your current locale. If automatic codepage chooser fails, use this option to manually set codepage number.
(example): Use "-mcp=437" for CP437

-slp: set Large Pages mode
-slt: show technical information for l (List) command
-snh: store hard links as links
-snl: store symbolic links as links
-sni: store NT security information
-sns[-]: store NTFS alternate streams
-so: write data to stdout
-spd: disable wildcard matching for file names
-spe: eliminate duplication of root folder for extract command
-spf: use fully qualified file paths
-ssc[-]: set sensitive case mode
-sse: stop archive creating, if it can't open some input file
-ssp: do not change Last Access Time of source files while archiving
-ssw: compress shared files
-stl: set archive timestamp from the most recently modified file
-stm{HexMask}: set CPU thread affinity mask (hexadecimal number)
-stx{Type}: exclude archive type
