Hi everyone,

I'm doing a little bourne shell program that makes
something installed automatically on my FreeBSD. But I
have a little problem: I want to be able to read every
caracter of a variable. For example: Suppose I have a
variale named TOTO and the content of TOTO is
"/toto/tata/foo". So if I do an echo the ouput is:
echo $TOTO
/toto/tata/foo

What I'm trying to do is to catch only "/foo" and put
it in another variable. So I tought that if someone
tell me how to read each caracter, I can loop over
each caracter, remember the positition of the last "/"
and then take all the caracters after that "/" and put
it in a variable.

Can somebody help me on this one? I hope I'm
sufficiently clear.

Thanks

Eric
