How can I see the output of the stderr of a program?

Assuming you mean 'only' the stderr output, you can redirect stdout to
/dev/null.  What you have left is stderr.

For instance:

/usr/local/bin/someprogram > /dev/null

or

/usr/local/bin/someprogram > someprogram.out 2>someprogram.err

the 2> redirects stderr.

By default, it should appear right on your terminal.
Why are you having trouble seeing it?

find out what the standard error of the program is or redirect it 2>&1
to standard out.

under normal circumstances, it's pretty simple.  just run the
program, and stderr will appear on the screen.

since you asked the question, though, i assume that you have
some special need.  are you in a graphical environment, or
do you need to separate stdout from stderr, or some other
special condition?
