unix security module


I’ve been reading this post:


and the poster uses this to get the password:

set pwrd to do shell script "security 2>&1 >/dev/null find-generic-password -gl " & Qlabel

I know that other options may be used besides the label. This seems to work for me when just using the label:

do shell script “security find-generic-password -wl QLabel”

Are the other things still needed (i.e. 2>&1 >/dev/null). Also, the -w instead of the -g option returns just the password. Was the -w option added to security after the above post?
