htop
by Hisham Muhammad <loderunner@users.sourceforge.net>
May, 2004 - September, 2005
Introduction
~~~~~~~~~~~~
This is htop, an interactive process viewer for Linux.
It requires ncurses. Tested with Linux 2.4 and 2.6.
Note that, currently, htop is _Linux_ specific -- it is based
on the Linux /proc filesystem. Contributions of ports to
other operating systems are welcome and will gladly be merged.
This software has evolved considerably during the last months,
and is reasonably complete, but there is still room for
improvement. Read the TODO file to see what's known to be missing.
Comparison between 'htop' and 'top'
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* In 'htop' you can scroll the list vertically and horizontally
to see all processes and full command lines.
* In 'top' you are subject to a delay for each unassigned
key you press (especially annoying when multi-key escape
sequences are triggered by accident).
* 'htop' starts faster ('top' seems to collect data for a while
before displaying anything).
* In 'htop' you don't need to type the process number to
kill a process, in 'top' you do.
* In 'htop' you don't need to type the process number or
the priority value to renice a process, in 'top' you do.
* In 'htop' you can kill multiple processes at once.
* 'top' is older, hence, more tested.
Compilation instructions
~~~~~~~~~~~~~~~~~~~~~~~~
This program is distributed as a standard autotools-based package.
See the INSTALL file for detailed instructions, but you are
probably used to the common "configure/make/make install" routine.
Keys
~~~~
Arrows,
[PgUp], [PgDn],
[Home], [End] - scroll process list

[F2], [S] - setup: configure header meters
[F3], [/] - incremental process search: type process name
[F4], [I] - invert sort order
[F5], [<] - select sorting by previous field
[F6], [>] - select sorting by next field
[F7], []] - increase process priority (superuser only)
[F8], [[] - decrease process priority
[F9], [k] - kill process (all tagged ones, or the current, if none is tagged)
[F10],[q] - quit
[F] - highlight follows process
