DESCRIPTION
7-Zip is a file archiver supporting 7z (that implements LZMA compression algorithm
featuring very high compression ratio), LZMA2, XZ, ZIP, Zip64, CAB,
RAR (if the non-free p7zip-rar package is installed), ARJ, GZIP, BZIP2, TAR, CPIO, RPM, ISO,
most filesystem images and DEB formats.
Compression ratio in the new 7z format is 30-50% better than ratio in ZIP format.
p7zip
is a gzip-like CLI wrapper script for 7-Zip, and handles only the 7z format (the native
format of 7-Zip), internally executing either
7za(1)
or
7zr(1)
command.
With no switches passed in the command line, each given
file
argument is compressed into
file.7z,
and then removed.
With the
-d
switch each passed
file
needs to end with the
.7z
extension and is decompressed. After the
decompression the original
file
is removed unless it contained more than one archived file.
When used without any
file
argument,
p7zip
reads data from the standard input and compresses (or decompresses in case of
-d)
it into the standard output.
SWITCHES
- -c, --stdout, --to-stdout
-
Write output on standard output.
- -d, --decompress, --uncompress
-
Decompress file.
- -f, --force
-
Skip some checks and force compression or decompression.
- -h, --help
-
Print usage.
- -k, --keep
-
Do not delete input file.
- --
-
Treat all subsequent arguments as file names, even if they start with a dash.
