SYNTAX

       htop

DESCRIPTION

       This program is a free (GPL) ncurses-based process viewer.

       It is similar to top, but allows to scroll the list vertically and hor-
       izontally to see all processes and their full command lines.

       Tasks related to processes (killing,  renicing)  can  be  done  without
       entering their PIDs.

INTERACTIVE COMMANDS

       The following commands are supported:


       Arrows, PgUP, PgDn, Home, End
            Scroll process list.

       Space
            "Tag":  mark a process. Commands that can operate on multiple pro-
            cesses, like "kill", will then apply over the list of tagged  pro-
            cesses, instead of the currently highlighted one.

       U    "Untag"  all processes (remove all tags added with the Space key).

       s    Trace process system calls: if strace(1)  is  installed,  pressing
            this  key  will  attach it to the currently selected process, pre-
            senting a live update of system calls issued by the process.

       F1, h
            Help screen

       F2, S
            Setup screen. There you can configure meters displayed on the  top
            side of the screen, as well as set various display options, choose
            among color schemes and select the layout of  the  displayed  col-
            umns.

       F3, /
            Incremental process search: type in part of a process command line
            and the selection highlight will be moved to it. While  in  search
            mode, pressing this key will cycle through matching occurrences.

       F4, I
            Invert sort order: if sort order is increasing, switch to decreas-
            ing, and vice-versa.

       F5, t
            Tree view: organize processes by parenthood, and layout the  rela-
            tions between them as a tree. Toggling the key will switch between
            tree and your previously selected sort view. Selecting a sort view
            "Kill" process: sends a signal which is selected in a menu, to one
            or a group of processes. If processes were tagged, sends the  sig-
            nal to all tagged processes.  If none is tagged, sends to the cur-
            rently selected process.

       F10, q
            Quit

       u    Show only processes owned by a specified user.

       M    Sort by memory usage (top compatibility key).

       P    Sort by processor usage (top compatibility key).

       T    Sort by time (top compatibility key).

       F    "Follow" process: if the sort order causes the currently  selected
            process  to  move  in  the list, make the selection bar follow it.
            This is useful for monitoring a process: this way, you can keep  a
            process  always  visible  on  screen. When a movement key is used,
            "follow" loses effect.

       K    Hide kernel threads: prevent the threads belonging the  kernel  to
            be displayed in the process list. (This is a toggle key.)

       H    Hide user threads: on systems that represent them differently than
            ordinary processes (such as recent NPTL-based systems),  this  can
            hide  threads  from userspace processes in the process list. (This
            is a toggle key.)

       Ctrl-L
            Refresh: redraw screen and recalculate values.

       Numbers
            PID search: type in process ID and the selection highlight will be
            moved to it.
