Re: Determining user ID

[Paul Krizak]

You could do something like:

groups:
   pgonedatabaseuser = ReturnsZero(/bin/sh -c 
${dblquote}/usr/bin/whoami | grep -q pgonedatabaseuser${dblquote})
   pganotherdatabaseuser = ReturnsZero(/bin/sh -c 
${dblquote}/usr/bin/whoami | grep -q pganotherdatabaseuser${dblquote})

(apologies for nasty e-mail wrapping)
