This flag shows the names of all the running processes, their process identification numbers (PIDs), the PIDs of their parents (PPIDs), and when they began (STIME). It also shows what terminal, if any, they're attached to (TTY), how much CPU time they've racked up (TIME), and the...
The TIMEFORMAT variable may be set to a format string that spec- ifies how the timing information should be displayed; see the description of TIMEFORMAT under Shell Variables below. Each command in a pipeline is executed as a separate process (i.e., in a subshell). Lists A list is a ...
Then, type the “kill -HUP [PID]” command into the terminal by replacing the PID of the current shell. In our case, specify the process id 22133 to kill the specified process: $ kill -HUP 22133 It terminates the Bash shell, and users can restart it using the “CTRL+ALT+T” command...
