I was barking up the wrong tree with sed.
sed has't any builtin macro to get current date, so it has to get it from
environment/command line, i.e., you have to execute "date" (which means a
new "sed") for every line, and you end up with a loop. Cheers J.A.Gutierrez,
you're correct.
Several people suggested awk variations like :
|awk '{printf("%s",$0); system("date");}'
But i went for the below for the simplier date format, cheers to Michael
Bradford for the body
#!/bin/ksh
touch ./VMSTAT_OUTPUT
vmstat 2 700 | while read LINE
do
echo " `date +\"%D %T\" ` $LINE" >> ./VMSTAT_OUTPUT
done

Subject: sed append a\ problem.
Managers,
I'm wanting to get vmstat to include the date, which is not a flag. I'm
trying not to stick it in a loop with an echo date etc, but instead have a
vmstat 5 720 (every 5 seconds for an hour). been piped into sed and
appending the date. to each line.
I'm having no luck with the syntax, any help much appreciated.
Cheers,
Carl Bavington
