I have csvde dump from active directory I process on my postfix mta. It takes output like this: "CN=Curtis xxx,OU=Domain Users,OU=xxx xxx,DC=xxx-xxx,DC=local",X400:c=US\;a= \;p=xxx xxx xxx\;o=Exchange\;s=xxx\;g=xxx\;;SMTP:Cxxx at xxx-xxx.com and should return a relay_recipient map in the form of: Cxxx at xxx-xxx.com OK The command I am using is: cat $1 | tr -d \" | tr , \\n| tr \; \\n | awk -F\: '/(SMTP|smtp):/ {printf("%s\tOK\n",$2)}' Everything up to the awk is working, it drops the smtp: but its putting OK's all over the darn place. Anyone familiar enough with awk and printf that can suggest why this happens? Thanks! jlc
