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.
