pstree is a command-line tool that displays a tree view of the running processes on a Linux system. It provides a hierarchical representation of processes, making it easy to visualize the relationships between them.
Understanding pstree
pstree works by traversing the process table, which contains information about all the running processes on the system. It starts with the init process, which is the parent of all other processes, and recursively displays its children and their descendants.
The output of pstree is a tree structure, with each line representing a process. The first column shows the process ID (PID), followed by the command name. The indentation of the line indicates the process's level in the hierarchy.
Using pstree
pstree is a versatile tool that can be used for various purposes, including:
