2013年9月17日 · xz -4e calls xz with the -4e compression option. (equal to -4--extreme) > filename.tar.xz directs the tarred and compressed file to filename.tar.xz; where -4e is, use your own compression options. I often use -k to --keep the original file and -9 for really heavy compression. -z to manually set xz to zip, though it defaults to zipping if not ...

tar's uppercase J switch uses XZ (whereas the lowercase j switch uses bzip2). The XZ_OPT environment variable lets you set xz options. This is now maximal. See man xz for other options you can set (-e/--extreme might give you some additional compression benefit for some datasets). XZ_OPT=-e9 tar cJf tarfile.tar.xz directory

Xz copies almost all the defects of gzip and then adds some more, like the fragile variable-length integers. Just one bit-flip in bit 7 of any byte of one variable-length integer and the whole xz stream comes tumbling down like a house of cards. Using xz for anything other than compressing short-lived executables is not advisable.

2017年3月2日 · My colleagues using mac or linux open xz files with this line: xz --decompress --stdout "file.csv.xz" On my pc, with windows 10, I get the following error: 'xz' is not recognized as an internal or external command, operable program or batch file. Is …

2014年3月7日 · If you want to use this in combination with tar just call export XZ_DEFAULTS="-T 0" before. or use smth like: XZ_OPT="-2 -T0" Compression. Multiprocessor (multithreading) compression support was added to xz in version 5.2, in December 2014. Decompression. Multiprocessor (multithreading) decompression support was added to xz in version 5.4.0, in ...

2019年9月24日 · If you look through the tooling provided by the xz RPM on RHEL/CentOS/Fedora distros this RPM includes a few helper wrapper scripts that you can enlist to make short work of this.

xz has become a bit of a standard when it comes to package management in recent years. the LZMA2 compression algorithm xz uses, is exceptionally efficient with text (and "text-like") data. I personally use it for pretty much anything, where computational encoding speed is not an issue ( xz decompresses much faster than compressing, it's ...

2022年7月18日 · I wanted to install Python 3.5.5, I only found compressed files as shown below. when I wanted to intall it using pip install Python-3.5.5.tar.xz or pip install Python-3.5.5.tgz I had these errors

2021年9月22日 · Like gzip (.gz) and bzip2 (.bz2), but unlike zip and rar, xz is a compression format, not an archive format. You can compress one file: 7z a -txz foo.xz foo This is equivalent to xz foo. Typically, to make a compressed archive, you make a tar archive and compress it.

Tools to compress/decompress xz and gzip files are also available on Windows systems, but are more commonly seen and used on UNIX systems. xz and 7zip are known to have a better compression algorithm than gzip, but use more memory and time to compress/decompress. This topic is nicely discussed here.
