Allocate 100% memory in VMware workstation prevent huge VMEM file

VMware Workstation creates VMEM files size eque to the memory settings of the VM.

To prevent create the VMEME file I set memory allocate to 100%.

First power off the VM.

Then open the [VM_NAME.vmx] file under the VM folder.

Add or update these parameters:
 

MemTrimRate = "0"
prefvmx.minVmMemPct = "100"
mainMem.useNamedFile = "FALSE"
sched.mem.pshare.enable = "FALSE"
prefvmx.useRecommendedLockedMemSize = "TRUE"

Fix keyboard lag/input delay on Ubuntu, Debian and Redhat in VMware workstation 17

I experiencing this problem with Ubuntu, Debian, Redhat in VMware workstation version 17.

I tried all these, none works:

• Enhanced keyboard on and off

Finally, turn on the "Virtualize IOMMU (IO memory management unit) under [Virtualization engin] under "Processors" like this fixed the issue.

Bash scrip check if another instance of my shell script is running

#!/bin/bash

# Check if another instance of my shell script is running
if [[ `pgrep -f $0` != "$$" ]]; then
	echo "Another instance of shell already exist! Exiting"
	echo "[$(date)] : $0 : Process is already running with PID $pid"
	exit 1
fi

# Rest of the script goes here
echo "[$(date)] : $0 : is now running..."

Explanation: 

1. $0 gives filename of your running script.
2. $$ gives PID of your running script.
3. pgrep searches for process by name and returns PID.
4. pgrep -f $0 searches by filename, $0 being the current bash script filename and returns its PID.
