-This script will compute peak memory usage of all processes running by a specific user
-To use this script, execute it before the launch of all processes you need to compute their peak memory usage
-The peak memory usage of each process will be save in a file inside the folder ./memusg
-The file name will be: processName_processId_processStartTime
-The file will contain two lines: first line contains memory usage in MBs, second line contains parent process ID, and the command which launched the process
-The script takes 5 parameters:
- Time interval (in seconds) between consecutive checks
2) Minimum memory (in MBs) size to track (avoid tracking any process whose memory peak does not exceed this value)
3) Flag to empty the ./memusg folder before starting ("clean" or "noclean")
4) User name whose owned processes need to be tracked (or "all" if you need to track all users)
5) The name of the tracked process (or "all" if you need to track all processes)
-The script is tested on both linux and mac
-Example usage (track all processes with > 20 MBs peak memory of user "aminallam" every 10 seconds):
bash ./memusg.sh 10 20 clean aminallam all
