Hi,

choose one of two ways:

Code:
sed 's/.*OK: \[\([^]]*\).*/\1/' <<< \
"Thu Dec  4 08:28:57 2008 : Auth: Login OK: [vyce6220] (from client LINKSYS3 port 12 cli 001644fc4838)"

or much easier:

Code:
IFS="[]" && read 1 2 3 <<< \
"Thu Dec  4 08:28:57 2008 : Auth: Login OK: [vyce6220] (from client LINKSYS3 port 12 cli 001644fc4838)"
echo $2
