How to correctly add a path to PATH?

I installed "perf" on Linux. But I can only use it by specifying the path: ~/bin/perf

I checked path by using echo and I found /bin is there.

What else should I do?

~/bin is not /bin. Add it to $PATH.

	but I got this, why? " `/home/paul/bin': not a valid identifier " – Anders Lind Mar 8 '12 at 7:26
	@AndersLind: get rid of the whitespace. It should be `export PATH=foo:bar:baz`, not `export PATH = foo:bar:baz`. Shells are sensitive to this sort of thing. – Alexios Mar 8 '12 at 11:17

You have to add ~/bin to $PATH. You can do it with this command :

export PATH="$PATH":~/bin

You can check your PATH variable with env :

env | grep  ^PATH=

Another way to check PATH variable is simply echo $PATH. – jofel Mar 8 '12 at 8:32
