 awk can do a little more to eliminate the second grep:
 
 setenv SSH_AUTH_SOCK `sockstat | grep "^${USER} " | awk '/ssh-agent/ { print $6 }'`
 
 The anchor before and space after the username in the grep are to make 
 it an exact match and not a subset ("jsm" versus "jsmith").  Although I 
 don't know what sockstat does with a username longer than eight 
 characters.

 It is.  Accuracy and precision are the goal.
