Hello All

I am trying to uncompress a .tar.xz file.

Can somebody suggest me a command as tar -Jxf <filename> gives me an error.

anusha@anusha-laptop:/usr/src/gcc-4.4$ tar -Jxf gcc-4.4.3.tar.xz
tar: xz: Cannot exec: No such file or directory
tar: Error is not recoverable: exiting now
tar: Child returned status 2
tar: Exiting with failure status due to previous errors
