pstree is a Linux command that shows the running processes as a tree [1] [2] [3]. It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid. It can also be installed in other Unix systems. In BSD systems, a similar output is created using ps -d, in Linux ps axjf [4] produces ...
It has since been available in illumos and reimplemented for the Linux and BSDs (DragonFly BSD, FreeBSD, NetBSD, and OpenBSD). It searches for all the named processes that can be specified as extended regular expression patterns, and—by default—returns their process ID. Alternatives include pidof (finds process ID given a program name) and ps.
The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory.
Shows all TCP connections with no DNS resolution (show IP addresses instead). netstat -al: Shows only listening sockets. netstat -aep: Also show PID and to which program each socket belongs, e adds extra info like the user. Run as root to see all PIDs. netstat -s: Shows network statistics. netstat -r: Shows kernel routing information.
For example, a PID namespace provides a separate enumeration of process identifiers within each namespace. Also available are mount, user, UTS (Unix Time Sharing), network and SysV IPC namespaces. The PID namespace provides isolation for the allocation of process identifiers (PIDs), lists of processes and their details. While the new namespace ...

Lennart Poettering and Kay Sievers, the software engineers then working for Red Hat who initially developed systemd, [2] started a project to replace Linux's conventional System V init in 2010. [17] An April 2010 blog post from Poettering, titled "Rethinking PID 1", introduced an experimental version of what would later become systemd. [18]
