useful little perl script to insert timestamps into your data stream / pipeline

Submitted by Aleksey Tsalolikhin on Thu, 2008-02-14 19:21.

I wrote this script to insert a timestamp into the pipeline. I call it "teetime" after /usr/bin/tee.

It can make vmstat more informative, for example:

vmstat 1 | teetime
