Search for processes by name, command, or PID. Search for multiple things at once by separating them with commas. For example, arm, x86 will return processes having arm or x86 as a substring of the name or command. You can use regular expressions too. For example, d$ will return a list of daemons (which tend to end in the letter d), while ^(\w+\.)+\w+$ will return a list of processes with reverse domain name notation, such as com.docker.vmnetd.
