what is bash? it is a kind of shell yes this is what i read and can understand, BUT sometimes i get confused when using it
for example when i do export a variable
i can find it exported
but when i login in another shell to see whether exported or not i can't find the variable
what is the difference between bash and opening a new shell ???? isn't bash supposed to open a new shell(session)???
why isn't variables exported through shells as with bash ???!!!!
