mail merge separate file per record

Microsoft Word has an excellent feature called Mail-Merge. If the query returns more than one record (say 4 for the sake of the example), then the resulting Word file has multiple copies of the document merged together in one file. It is possible to have Word create a seperate file for each record using this add-on.

find dead processes

The 8th column of ps aux command will list the status of the process.

ps aux | awk '{if ($8 ~ "D") print $0}'

Here is a list of the various process statuses and what they mean:

D – Uninterruptible sleep (usually a critical system process, a process that cannot be killed without rebooting)
R – Running
S – Interruptible sleep (waiting for an event to complete)
T – Stopped
Z – Defunct (“zombie”) process
