How to view process hierarchy?

To view the process hierarchy in a Unix-like operating system, you can use the pstree command. This command provides a visual representation of the process hierarchy in a tree-like format, showing how processes are related to each other.

Here’s how to use it:

Open your terminal.
Type the following command and press Enter:
```
pstree
```

This will display the processes in a hierarchical structure. If you want to see more details, you can use options like -p to include process IDs:

pstree -p

This will give you a clearer view of the relationships between parent and child processes.
