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.
-
-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.
