you don't need single quotes, in your example it probably inhibits to do what you want. Better use double quotes instead.

Not related but you should put the . at the end of the PATH rather than the beginning to prevent spoofing of real Unix programs.  Takes a little longer to run but better for security.

I am sorry, but what do you mean by "to prevent spoofing of real Unix programs"?

> .. prevent spoofing of real programs ..
means that if you have . first in your PATH, some bad people might place programs like  ls, pwd, pws, etc.
somewhere in the filesystem, and these progs might do what *they* want and what you expect, 'cause they are found in PATH first before the real programs in /bin or /usr/bin

That's all, off-topic ...
