What command can show all users' processes in a formatted output?

The command that shows all users' processes in a formatted output is "ps -ef". This command is part of the process management utilities found in Unix and Linux operating systems. The "ps" command itself is used to display information about currently running processes, and the arguments "-ef" modify its behavior.

The "-e" flag tells the command to display processes for all users, rather than just the processes belonging to the user who is executing the command. The "-f" flag stands for "full-format listing," which means that the output includes extensive details about each process, such as the user that owns the process, the process ID (PID), parent process ID (PPID), start time, and the command line that initiated the process. This detailed output is helpful for system administrators and users who need to monitor and analyze system performance and resource usage.

Using other commands like "kill" focuses on terminating processes, while "grep" is utilized for searching within text streams, and "more" is a pagination tool used to view text files page-by-page. Therefore, these do not serve the purpose of listing or formatting user processes.
