Memory/Swap Usage Per Process Script

This script displays the memory/swap usage for each process in MB. Additionally, it informs the user about the total memory/swap usage and utilization percentage for the system.

Requirements

• Linux OS
• Bash shell
• Commands: free, awk, getent

Usage

1. Make the script file (saved as something like swap_usage.sh) executable:

   chmod +x memory_usage.sh
   chmod +x swap_usage.sh
   

2. Execute the script:

   ./memory_usage.sh
   ./swap_usage.sh
   

3. The output will be displayed in the following format:

   User:     root - PID:   1234 - Swap Used:   2.20 MB - Command: /path/to/command arg1 arg2
   User:    user1 - PID:   5678 - Swap Used:   1.10 MB - Command: /path/to/another-command arg1
   ...
   Total Swap: 4096.00 MB
   Used Swap: 100.00 MB
   Swap Usage: 2.44%
   

Notes

• It's recommended to run this script with root permissions to gather information from all processes.
• The script is primarily designed for Linux environments.
