Htop command9/27/2023 The data is continuously updated, which allows you to follow the processes in real-time. The top command is useful to check memory and CPU usage per process. st: Time stolen from a virtual machine. Before Linux 2.5.41, this includes IO-wait time. us: Time spent running non-kernel code.CPU – These are percentages of total CPU time.cs: number of context switches per second.in: number of interrupts per second, including the clock.bo: Blocks sent to a block device (blocks/s).bi: Blocks received from a block device (blocks/s).buff: the amount of memory used as buffers.b: number of processes in uninterruptible sleep.r: number of processes waiting for run time.The detailed description listed below provides an explanation for each value in case you need assistance in analyzing the results. The table below lists the most useful variations of the free command. Share Improve this answer Follow answered at 19:08 DRAD 41 2 1) The -p is available in Htop. For example: top -p (pgrep -d',' -f 'geany') This will launch top with only processes for geany shown. The free command has multiple options to format the output so that it better matches your requirements. You can do this in top, not htop that I'm aware of. The key figure being the available value as it displays how much memory is still available for running new applications. Memory reserved by the OS to allocate as buffers when process need themĮstimation of how much memory is available for starting new applications, without swapping.Ĭompared to the /proc/meminfo file, the free command provides less information. Unused memory (free= total – used – buff/cache) Memory currently in use by running processes (used= total – free – buff/cache) I browsed through man htop, but unfortunately I cannot see such command line/option.The data represents the used/available memory and the swap memory figures in kilobytes. This would be useful if integrating the command into, say, a tmux session. and get the exact same behavior as if hitting F4 and typing in the terminal UI. Now, I would like to start htop with filtering already from the command line, say: htop -filter="gphoto2" I'm already aware that I can start htop, and then hit F4 for filter, then type or paste a process name search query (say, gphoto2 for looking for rvice), and then htop filters the shown processes: if there is no such process, it shows nothing, if it starts later, htop shows it then.
