[sllug-members]: stderr + less

[Doug Beattie]

If you want even more control, as in you want your keystrokes to be
input to the program instead of "less", and you want the output to
be viewable after "foo" stops running, you could do the following:
 foo 2>&1 | tee -a <somefilename>

Stderr (fd 2) of foo is sent to foo's stdout (fd 1) then piped to the
"tee" program which allows the output to go to both the screen and to
a file simultaneously. "foo" still continues to gets its input (fd 0)
or stdin from the keyboard.
After the fact, you can then "vi" or "less" the file the "tee" sent the
output to.
