Introduction

This is htop, an interactive process viewer.
2006-07-11 06:20:33 +00:00
It requires ncurses. It is tested with Linux 2.6,
but is also reported to work (and was originally developed)
with the 2.4 series.
2006-03-04 18:16:49 +00:00
Note that, while, htop is Linux specific -- it is based
on the Linux /proc filesystem -- it is also reported to work
with FreeBSD systems featuring a Linux-compatible /proc.

This is, however, unsupported. Contact the packager for your
system when reporting problems on platforms other than Linux.

This software has evolved considerably during the last years,
2006-03-04 18:16:49 +00:00
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'
2014-02-03 11:11:08 +00:00
-----------------------------------
* 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
2014-02-03 11:11:08 +00:00
probably used to the common `./configure`/`make`/`make install` routine.
When fetching the code from the development repository, you need
to run the `./autogen.sh` script, which in turn requires autotools
to be installed.
2006-03-04 18:16:49 +00:00
See the manual page (man htop) or the on-line help ('F1' or 'h'
inside htop) for a list of supported key commands.
if not all keys work check your curses configuration.
