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.

19.

Unless B<--stdout> is specified, I<files> other than B<-> are written to a new file whose name is derived from the source I<file> name:

21.

When compressing, the suffix of the target file format (B<.xz> or B<.lzma>) is appended to the source filename to get the target filename.

22.

When decompressing, the B<.xz> or B<.lzma> suffix is removed from the filename to get the target filename. B<xz> also recognizes the suffixes B<.txz> and B<.tlz>, and replaces them with the B<.tar> suffix.

23.

If the target file already exists, an error is displayed and the I<file> is skipped.

24.

Unless writing to standard output, B<xz> will display a warning and skip the I<file> if any of the following applies:

25.

I<File> is not a regular file. Symbolic links are not followed, and thus they are not considered to be regular files.

26.

I<File> has more than one hard link.

27.

I<File> has setuid, setgid, or sticky bit set.

28.

The operation mode is set to compress and the I<file> already has a suffix of the target file format (B<.xz> or B<.txz> when compressing to the B<.xz> format, and B<.lzma> or B<.tlz> when compressing to the B<.lzma> format).
