Which shell interprets `{}'?  I have never seen one.

`egrep' is deprecated.  From
http://pubs.opengroup.org/onlinepubs/009604499/utilities/grep.html:

"This grep has been enhanced in an upwards-compatible way to provide
the exact functionality of the historical egrep and fgrep commands as
well. It was the clear intention of the standard developers to
consolidate the three greps into a single command."

From `man grep' of GNU grep:

"In addition, the variant programs egrep and fgrep are the same as
grep -E and grep -F, respectively.  These variants are deprecated, but
are provided for backward compatibility."
