[Bug 1291020] Re: unlzma -l fails to recognize files created by lzma

[Mathew Hodson]

This isn't a bug. Maybe it's a feature request.

The message gives all the information you need. The --list function (or
-l) works only on .xz files not .lzma files.

The command lzma is equivalent to xz --format=lzma so it creates a .lzma
file. If you want to be able to print information about your compressed
file, you need to create it with xz (--format=xz or --format=auto) foo.

$ xz foo
$ xz -l foo.xz 
Strms  Blocks   Compressed Uncompressed  Ratio  Check   Filename
    1       0         32 B          0 B    ---  CRC64   foo.xz
