![]() A value of '-' in all the rows indicates that a column is unsupported on your system, orĬurrently unimplemented in htop. The following columns can display data about each process. Numbers PID search: type in process ID and the selection highlight will be moved to it. (This is a toggle key.)Ĭtrl-L Refresh: redraw screen and recalculate values. Hide user threads: on systems that represent them differently than ordinary processes (such as recent NPTL-based systems), this can hide threads from Hide kernel threads: prevent the threads belonging the kernel to be displayed in the process list. When a movement key is used, "follow" loses effect. Monitoring a process: this way, you can keep a process always visible on screen. "Follow" process: if the sort order causes the currently selected process to move in the list, make the selection bar follow it. Sort by processor usage (top compatibility key). Sort by memory usage (top compatibility key). Show only processes owned by a specified user. When a subtree is collapsed a " " sign shows to the left of the process name.Ī (on multiprocessor machines) Set CPU affinity: mark which CPUs a process is allowed to use. When in tree view mode, expand or collapse subtree. Invert the sort order: if sort order is increasing, switch to decreasing, and vice-versa. If none is tagged, sends to the currently selected process. If processes were tagged, sends the signal to all tagged This can only be done by the superuser.į8, [ Decrease the selected process's priority (add to 'nice' value)į9, k "Kill" process: sends a signal which is selected in a menu, to one or a group of processes. The current sort field is indicated by a highlight in the header.į7, ] Increase the selected process's priority (subtract from 'nice' value). Selecting a sort view will exit tree view.į6, Select a field for sorting. Toggling the key will switch between tree and your previously To cancel filtering, enter theį5, t Tree view: organize processes by parenthood, and layout the relations between them as a tree. Mode, pressing F3 will cycle through matching occurrences.į4, \ Incremental process filtering: type in part of a process command line and only processes whose names match will be shown. The currently selected (highlighted) command will update as you type. Select which columns are displayed, in which order.į3, / Incrementally search the command lines of all the displayed processes. Trace process system calls: if strace(1) is installed, pressing this key will attach it to the currently selected process, presenting a live update ofĭisplay open files for a process: if lsof(1) is installed, pressing this key will display the list of file descriptors opened by the process.į2, S Go to the setup screen, where you can configure the meters displayed at the top of the screen, set various display options, choose among color schemes, and Untag all processes (remove all tags added with the Space key). Commands that can operate on multiple processes, like "kill", will then apply over the list of tagged processes, instead of the The following commands are supported while in htop:Īrrows, PgUP, PgDn, Home, End Scroll the process list. v -version Output version information and exit s -sort-key COLUMN Sort by this column (use -sort-key help for a column list) Start working thread for pagemap memory stats u -user=USERNAME Show only the processes of a given user C -no-color -no-colour Start htop in monochrome mode d -delay=DELAY Delay between updates, in tenths of seconds Mandatory arguments to long options are madatory for short options too. ![]()
