Timing problem

This works on GNU/Linux:

[jcast@cate1-208 jcast]$ (time ls) 2>&1 | egrep '^real'
real	0m0.020s

The redirections `|' and `>' have higher precidence in bash than
`time'.  The parentheses are required to force the precedence you
want.  (Actually, they are slightly more complicated, but that's the
gist.)  However, `time' prints to the standard error, so you need to
redirect that into you pipe, with `2>&1'.  If you just want to send
the output to a file, use `2> foo'.
