Yes, ~/.bashrc is the place to put aliases... because then they are 
loaded whenever you log in.  If this isn't the behavior you want, then 
you can put them somewhere else, e.g., in ~/bin/aliases, but then you'll 
have to invoke them yourself.  This can be done with either of these 
commands:

source ~/bin/aliases
or
. ~/bin/aliases

(Note that "~/bin/aliases" is an example name I made up. Just about any 
normal filename can be given.)

If you edit ~/.bashrc, including new aliases in it, you can use the same 
commands as above to read those new aliases into the current environment 
with:

source ~/.bashrc
or
. ~/.bashrc

Then you don't have to log out and then log back in to put your new 
aliases into effect.
