Absolutely. So post what *YOU* have written/done/tried so far, and tell us where you're stuck; we can certainly HELP you after that.

Otherwise, you need to read the "Question Guidelines" link in my posting signature. We will be happy to help you, but we aren't going to write scripts for you. You, personally, need to show your efforts.

Code:

#!/bin/bash

please insert your code that you have already written so some one hopefully can guild you ...

i suggest you look at monitorix.
it's a perl script and how it works is very transparent.
you can easily rip out what you need.

while true; do
    echo "$(date '+%Y-%m-%d %H:%M:%S') $(free -m | grep Mem: | sed 's/Mem://g')" >> `date "+%d%m%Y"`.txt
    sleep 30
done

This is my Code, is Working for me Now

Thanks

Tools like Nagios have already built-out an infrastructure for many types of system monitoring tasks.

If you're wanting to study "memory use," I suggest that the best way to do it is to build some logging capability into your applications-of-interest, then to perform offline statistical analysis of these data. There are two significant sources of error which can occur if you try to do it in real time:

The Presence of the Experimenter ... Your measuring process will either directly measure itself, or it will measure an environment that is being influenced by its own presence there, or both.
Linux is Lazy™ ... If there is right now no pressure for the memory resource, Linux won't clean-up after you. Why should it take the time?

There's also the problem of practical irrelevance. It's like measuring the number of cars on a street at a particular moment, when what you really want to know is how much effect congestion is having on the people who are trying to drive those streets. We've learned that you don't have to do this continuously: we can use random sampling and get a statistically-valid result. And what we would measure is some kind of thing like "number of requests processed" and "time required to complete (say) 1,000 requests." We probably would look more at the standard deviation than the average, or we might set up a "pass/fail" test to determine how often the process did or did not meet some arbitrary but meaningful deadline.
