I am having a problem with this command:
address@hidden:~/Downloads/rtl8712_8188_8191_8192SU_usb_linux_v2.6.6.0.20120405/driver$ tar -xvcf rtl8712_8188_8191_8192SU_usb_linux_v2.6.6.0.2012040.tar.gz
tar: You may not specify more than one `-Acdtrux' option
Try `tar --help' or `tar --usage' for more information.

tar: You may not specify more than one `-Acdtrux' option
I do not understand '-Acdtrux'. Could you please explain this to me and how to make it work.
