Linux commands (and most other things in Linux-land) are case-sensitive. So
echo $path is
not echo $PATH.
When we suggest command input, we usually mean
exactly what we type. I notice that you confused
ln with
in before, which (my apologies
) I didn't notice. (So forget all my angst about failed installation. Again, sorry.
) I've changed to a
serif font so such things are easier to see. (I prefer the cleaner look of
sans serif, but I guess clarity is better than clean.)
Usually you can highlight a suggested command, copy it with a <ctrl>-c, and paste it into your terminal window with a <shift>-<insert>. (Not the Windows standard <ctrl>-v -- the <shift>-<insert> is, I believe, one of the few Motif standards that were not copied into the Windows OS.
)
By the way, have you noticed the clipboard tool that lets you select which of the last several (5, I think, is the default) "copy" results your next "paste" will use?
