ps -e
2. Display Processes in a Tree Format
ps -e --forest
3. Show Processes for a Specific User
ps -u username
4. Display Detailed Information About Processes
ps -ef
5. Find Processes by Name or PID
ps -C process_name ps -p PID
6. Show Threads of a Process
ps -T -p PID
7. Display Processes in Real-Time
watch -n 1 'ps -e --forest'
8. Check Memory Usage of Processes
ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head
9. Kill a Process Using `ps` and `kill`
kill $(ps -ef | grep 'process_name' | awk '{print $2}')
10. Monitor CPU and Memory Usage
