I have a tarball file who has the file name extension tar.bz2. I can extract it to my user folder. But I see its usage said that it is under /opt folder. I have tried extract it with
sudo bzip2 -cd ~/Downloads/gcc-linaro-4.7-2013.12.tar.bz2 | tar xvf -
but it still cannot create folder under /opt
I am new to Linux. It reminds me to login as a root user? but I am not clear what does that really mean.
Could you help me on that?
