How to monitor peak memory usage?

How to monitor peak memory usage?# Unix - 噫吁兮，危乎高哉

Currently I use "top". However, is there any way to
capture it into a file so that I can read it later.
This is because I need to run a batch of jobs by a script.
I can't monitor all of them. I want to have a program
do it automatically and write the peak memory usage for
each of the job to a file.
Thanks.

"top" in batch mode (option "-b") can be redirected to a file.
But in order to do what you want, you have to invoke "top" repeatedly.
A simple but ugly way: write a shell script, call "top" periodically
and ">>" output to a file. You can filter out unwanted lines.
On systems that support /proc, you can write your own program to read
the /proc//status file and keep track the peak usage.
