date increment in file

[Jim Gerken]

I put he following into a file called "CPU"

echo "PID USER CPU% MEM_SIZE COMMAND"
while true
do
UNIX95= ps -eo "pid ruser pcpu vsz=Kbytes" -o comm | grep oracleD5751
sleep 10
done | sed 's;^;'$(date +'%m%d%H%M%S')' ;'

I execute this file to put the contents into a log.

date > cpu.log ; cpu >> /tmp/junk/cpu.log

However the date time stamp on the output never increments. It prints the first date time and then repeats it with each interation? Any thoughts...

Hi,

Until your while statement is completed, your sed won't get executed?.

You need to put the date command inside the loop.

Any thoughts on how I can change things around so the time increments each time the statement runs??

Hi:

You can achieve this with:

#!/usr/bin/sh
echo "PID USER CPU% MEM_SIZE COMMAND"
while true
do
UNIX95= ps -eo "pid ruser pcpu vsz=Kbytes" -o comm | (echo `date +'%m%d%H%M%S'`;grep vhand)|xargs
sleep 10
done

Hi (again):

Sorry, substitute 'oracleD5751' for 'vhand' [which I used to test :-)]

#!/usr/bin/sh
echo "PID USER CPU% MEM_SIZE COMMAND"
while true
do
UNIX95= ps -eo "pid ruser pcpu vsz=Kbytes" -o comm |(echo `date +'%m%d%H%M%S'`;grep oracleD5751)|xargs
sleep 10
done

Hi,

I would do this

FILE=/tmp/junk/cpu.log
echo "DATE PID USER CPU% MEM_SIZE COMMAND" > $FILE
while true
do
printf "$(date +'%m%d%H%M%S') " >> $FILE
UNIX95= ps -eo "pid ruser pcpu vsz=Kbytes" -o comm | grep oracleD5751 >> $FILE
sleep 2
done
