Can't run tmux although it's installed [duplicate]

Question

I compiled tmux from source on Ubuntu 12.04 and it is installed in /usr/local/bin/tmux by default.

However, when I type tmux in terminal I get the following message:

$ tmux
-bash: /usr/bin/tmux: No such file or directory

• How do I fix this? And how to install it in another location the next time?
• Is there any difference between putting it in /usr/bin or /usr/local/bin?

Answer 1

I found a solution. I just needed to open a new bash session.

Just type "bash" in console and you're ready to go.
