im gonna get linux sometime and i just wanna make sure i dont screw up too bad. theres a few files that i wanna install onto linux, mainly tar.gz and tar.bz2 files. to extract and install tar.gz files, do u:
(root)
cd /tmp
tar -zxvf [tar.gz file]
./install --prefix=/opt
(user)
cd /opt/[extracted filename]
./setup
[follow instructions]
is this how u install tar.gz files
and tar.bz2 files? tar.gz files seem pretty easy to install, but if its the same for the smaller-sized bz2 files, then im definitely downloading only bz2 files. does /tmp exist already and does it auto delete its files? so many ?'s, i just dont wanna start a buncha new threads.

oh, and do u hafta install the thingy into /opt?
