Ok but I have another question concerning gcc. I would like to have 2

The same way you'd choose between any two programs in different
locations.
You could adjust your $PATH or write a script which calls the one you
want.
I have a handful of versions installed in ~/gcc/ and invoke them via a
script like
#!/bin/bash
${ver:=4.7}
${libdir:=lib64}
$HOME/gcc/$ver/bin/g++ -Wl,-rpath,$HOME/gcc/$ver/$libdir -Wall -g "$@"
I see in .bash_profile that there is a PATH variable set. I have to put
all my binaries in /usr to get the shell to recognize it. I know nothing
about bash and would like to run a script that would allow me to simply run
a script that would switch back and forth between compilers, assemblers, and
the linker. Maybe 2 scripts. But I can't find the file that lists all my
path data. env shows the path as does echo $PATH. I always log in as root
anyway. If I want single user mode I add init=/bin/bash to the kernel switch
of grub.
