* The default dictionary size values for LZMA/LZMA2 compression methods
were increased
* 7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5.
* APM and HFS support was improved.
* If an archive update operation uses a temporary archive folder and
the archive is moved to the destination folder, 7-Zip shows the progress of moving
the archive file, as this operation can take a long time if the archive is large.
* The bug was fixed: 7-Zip File Manager didn't propagate Zone.Identifier stream
for extracted files from nested archives (if there is open archive inside another open
archive).
* Some bugs were fixed.

.SH 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.
|
|
.PP
|
|
.B 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
|
|
.BR 7za (1)
|
|
or
|
|
.BR 7zr (1)
|
|
command.
|
|
.PP
|
|
With no switches passed in the command line, each given
|
|
.I file
|
|
argument is compressed into
|
|
.IR file.7z ,
|
|
and then removed.
|
|
.PP
|
|
With the
|
|
.B \-d
|
|
switch each passed
|
|
.I file
|
|
needs to end with the
|
|
.I .7z
|
|
extension and is decompressed. After the
|
|
decompression the original
|
|
.I file
|
|
is removed unless it contained more than one archived file.
|
|
.PP
|
|
When used without any
|
|
.I file
|
|
argument,
|
|
.BR p7zip
|
|
reads data from the standard input and compresses (or decompresses in case of
|
|
.BR \-d )
|
|
it into the standard output.
|
|
