Other tools that I should have mentioned:

1.  A text mode editor that works over SSH.  (Another bike shed topic; I 
use Vim.)

2.  A version control system.  (Yet another; I use CVS.)

I've settled on the following languages/ tools, and think of them in 
levels of complexity (from highest to lowest):

     Higher-Order Perl [1]
     Bourne shell, Make

The lower levels are suited for ROM monitors, interpretors, kernels, 
device drivers, file systems, communications stacks, shells, editors, 
lexers, parsers, compilers, interpreters, etc. -- e.g. software that 
requires maximal efficiency (space, time) and/or must be programmed 
"close to the hardware".

The upper levels reduce complexity, making it easier for human beings to 
write powerful and sophisticated programs that work correctly.  If you 
learn a little C++, a little Perl, a little Python, a little Ruby, etc., 
you will never reach the highest levels.  Therefore, I'd advising 
picking one high-level language and mastering it (similar to martial 
arts or musical instruments).
