COMMAND ALIASES

10.

B<unxz> is equivalent to B<xz --decompress>.

11.

B<xzcat> is equivalent to B<xz --decompress --stdout>.

12.

B<lzma> is equivalent to B<xz --format=lzma>.

13.

B<unlzma> is equivalent to B<xz --format=lzma --decompress>.

14.

B<lzcat> is equivalent to B<xz --format=lzma --decompress --stdout>.

15.

When writing scripts that need to decompress files, it is recommended to always use the name B<xz> with appropriate arguments (B<xz -d> or B<xz -dc>) instead of the names B<unxz> and B<xzcat>.

17.

B<xz> is a general-purpose data compression tool with command line syntax similar to B<gzip>(1) and B<bzip2>(1). The native file format is the B<.xz> format, but the legacy B<.lzma> format used by LZMA Utils and raw compressed streams with no container format headers are also supported. In addition, decompression of the B<.lz> format used by B<lzip> is supported.

18.

B<xz> compresses or decompresses each I<file> according to the selected operation mode. If no I<files> are given or I<file> is B<->, B<xz> reads from standard input and writes the processed data to standard output. B<xz> will refuse (display an error and skip the I<file>) to write compressed data to standard output if it is a terminal. Similarly, B<xz> will refuse to read compressed data from standard input if it is a terminal.
