Introduction
|
|
------------
|
|
|
|
This is `htop`, an interactive process viewer.
|
|
It requires `ncurses`. It is developed primarily on Linux,
|
|
but we also have code for running under FreeBSD and Mac OS X
|
|
(help and testing are wanted for these platforms!)
|
|
|
|
This software has evolved considerably over the years,
|
|
and is reasonably complete, but there is always room for improvement.
|
|
|
|
Comparison between `htop` and classic `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](/INSTALL) file for detailed instructions, but you are
|
|
probably used to the common routine:
|
|
|
|
./autogen.sh && ./configure && make
|
|
|
|
If you want to replace currently installed version of `htop` use `--prefix` flag. `--prefix=/usr`
|
|
will install `htop` into `/usr/bin/htop`.
|
|
|
|
./autogen.sh && ./configure --prefix=/usr && make
|
|
make install
|
|
|
|
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.
