This is somewhat a Grandma question, but nevertheless, I can't really figure it out.
It's the following: I log in to a remote machine via ssh. There (for example!) I try to set LD_LIBRARY_PATH appropriately. This is often done with
export but on the console I get from ssh,
export leads to
"Command not found". I type then
bash and now I can use export.
On the other hand, I don't need to enter the bash terminal to execute sh-scripts and makefiles which contain for example the
export command but can do it right from the console I get when entering via ssh.
I would be glad if someone could explain me this in a few words! Or how can I find out more?
