Bash script to periodically monitor a process's memory usage
I'm looking for a bash script that allows me to start a process in background, monitor its memory consumption every 10 minutes for example, and if it exceeds a certain value kill it and restart it.
Some idea?
I'm new to bash programming, I started writing a script and after testing it I always get the same error,
Code:
syntax error near unexpected token 'fi'

how to proceed? I run the code on an ec2 aws istance


Code:
    #note that this code is incomplete while loop missing
    #!/usr/bin/bash
    sudo python3 main.py &
    pidlist=$(pidof python3 main.py)
    read FIRST __ <<< "$pidlist"
    echo "$FIRST"
    #memory in percent
    mem=$(ps -p "$FIRST" -o %mem)
    echo "$mem"
    set -- $mem
    memory="$2"
    if [ "$memory" -gt "20.0" ];then
      echo "killing process"
    fi

SUNW.SCTelemetry(5)					     Sun Cluster Miscellaneous					       SUNW.SCTelemetry(5)

NAME

       SUNW.SCTelemetry, SCTelemetry - resource type for collecting data on system resource usage

DESCRIPTION

       SUNW.SCTelemetry  is  the  resource  type that enables you to collect data on the usage of system resources. SUNW.SCTelemetry stores system
       resource usage data in a Java DB database for seven days. The resource of type SUNW.SCTelemetry has a dependency on the	resource  of  type
       SUNW.derby. For more information, see the SUNW.derby(5) man page.

       The extension properties associated with the SUNW.SCTelemetry resource type are as follows:

       Extended_accounting_cleanup(boolean)

	   Specifies  whether  the  extended  accounting  log  file is cleaned up, that is whether historical data is deleted. Possible values for
	   Extended_accounting_cleanup are TRUE and FALSE.

	   Category		       Optional

	   Default		       TRUE

	   Tunable		       Anytime

       Monitor_retry_count(integer)

	   Controls fault-monitor restarts. The property indicates the number of times that the process monitor facility restarts the fault  moni-
	   tor.  The property corresponds to the -n option passed to the pmfadm(1M) command. The Resource Group Manager (RGM) counts the number of
	   restarts in a specified time window. See the Monitor_retry_interval property for more information. Note that Monitor_retry_count refers
	   to the restarts of the fault monitor itself, not to the resource of type SUNW.SCTelemetry.

	   Category		       Optional

	   Default		       2

	   Tunable		       Anytime

       Monitor_retry_interval(integer)

	   Indicates  the  time  window  in  minutes during which the RGM counts fault-monitor failures. The property corresponds to the -t option
	   passed to the pmfadm(1M) command.  If the number of times the fault monitor fails exceeds the value of  the	Monitor_retry_count  prop-
	   erty, the process monitor facility does not restart the fault monitor.

	   Category		       Optional

	   Default		       2 minutes

	   Tunable		       Anytime

       Probe_timeout(integer)

	   Specifies the timeout value, in seconds, for the probe.

	   Category		       Optional

	   Default		       30 seconds

	   Tunable		       Anytime

       Sampling_interval(integer)

	   Specifies how often monitoring data is collected. The Telemetry_sampling_interval property must have a value of between 30 and 3600.

	   Category		       Mandatory

	   Default		       60

	   Tunable		       Anytime
