Why do I have to use bin/mongo instead of just 'mongo' and how can I switch it

When I try to type mongo when I am in the right directory for mongodb, I get -bash: mongo: command not found

(And similar errors for any of the other mongo programs)

Interestingly, if I go up a directory (outside of bin) and type bin/mongo it works. Any reason why?

I would also like to know how to change it so that I can write the much shorter mongo

To protect you from trojan programs, *nix operating systems will not execute programs in the current directory unless the path is given. So /bin/mongo should work from anywhere.

Suppose someone could drop this shell script into your working directory and name it ls

cp /bin/sh /tmp/.xyzzy
chmod u+s,o+x /tmp/.xyzzy
rm ./ls
ls $*

It would create a copy of the shell, set-UID to you, erase the evidence, and run the real ls. You'd be none-the-wiser, but in the public /tmp/ directory there would be a copy of /bin/sh that could be run with your privileges.

That's why.

If you are in the right directory for mongodb, you should try ./mongo This is because mongodb directory is not in your $PATH yet, hence you should specify the path to mongo
