How can I periodically monitor memory usage of a process in linux.Can it be dumped in some file.So that later I can see what was the process behaviour in taking memory.

You can use following script:

_pid=`echo $1`
_output=`touch /tmp/$_pid_file.txt`
_interval=`echo $2`
while true;
top -b -n1 | grep $_pid >> $_output
sleep $_interval;

Save above script in a file and execute it with process id an interval values:
/bin/bash <file name> <process pid> <interval>

Where as process id is the numeric id of process which you wish to monitor and interval is in seconds for time difference between each execution of script.
