tlz).Īfter successfully compressing or decompressing the file, xz copies the owner, group, permissions, access time, and modification time from the source file to the target file. The operation mode is set to decompress and the file doesn't have a suffix of any of the supported file formats (.The operation mode is set to compress and the file already has a suffix of the target file format (.File has setuid, setgid, or sticky bit set.Symbolic links are not followed, and thus they are not considered to be regular files. Unless writing to standard output, xz displays a warning and skip the file if any of the following applies: If the target file already exists, an error is displayed and the file is skipped. lzma suffix is removed from the file name to get the target file name. lzma) is appended to the source file name to get the target file name. When compressing, the suffix of the target file format (.Unless -stdout is specified, files other than " -" are written to a new file whose name is derived from the source file name: Similarly, xz will refuse to read compressed data from standard input if it is a terminal. xz will refuse (display an error and skip the file) to write compressed data to standard output if it is a terminal. If no files are given or file is specified as a dash (" -"), xz reads from standard input and writes the processed data to standard output. Xz compresses or decompresses each file according to the selected operation mode. lzma format used by LZMA Utils and raw compressed streams with no container format headers are also supported. Xz is a general-purpose data compression tool with command line syntax similar to gzip and bzip2.
