Extracting tar.xz

nownebie · 08-01-2012, 07:13 AM

Hi,

i need your help what to do next. Please read this text.
Extract the images using "tar -xvf IMAGE.tar.xz" -C /mnt" (replace "IMAGE" with the current Fortress Linux
image). I have a tar.xz file on usb stick. I have no idea what to do. I am getting error no such file or directory.

Thanks.

Judging from the error message it seams you are using the wrong path. Please change to the directory where the file resides and give the output of pwd.
What I also find strange is that the wikipedia entry of .xz tells to use the option -J for xz archives. So it might also be that the options your using with tar might be wrong.

You can determine the type of file with the file command; see the manpage for 'file'. Once determined, you can strip of the first layer of your file and run file again to figure out what you have now. Etc etc.

I assume that you are aware that extensions have no meaning in Linux; anybody can call it anything

So from the filename, one can not always determine what it is.

Hi,
i have that file on usb stick.I think it is sdb1. pwd output is /root.

So if the output is /root, this would mean you missed the part where zhjim said, "Please change to the directory where the file resides"

This means, change to where sdb1 is mounted, something like /media/<name of drive>. From here you can issue your tar command
