ps - (process statement) is a no-brainer, it provides a snapshot of currently running process, we get information like PIDs, CPU usage, memory usage and more.
```bash
ps aux # Show all processes with detailed information
ps -ef # Another format to show all processes
```
pidof is used to get the process ID (PID) of a running program by specifying its name.
```bash
pidof apache2 # Finds the PID of the Apache web server process
```
top provides a real-time view of all running processes. It allows users to filter and sort inofrmation
```bash
top

lsof provides list of open files and the processes that opened them. Since everything in a Linux is a file(even network sockets) this will be seful in identifying the processes that are using specific files or ports.
```bash
lsof /var/log/syslog # Find the process that has the syslog file open
lsof -i :80 # Find the process using port 80
```
