Linux commit 06eb61844d841d0032a9950ce7f8e783ee49c0d0 ("sched/debug:
Add explicit TASK_IDLE printing") exposes kthreads idling using
TASK_IDLE in procfs as "I (idle)".
Until now, when sorting the STATE ("S") column, htop used the raw
value of the state character for comparison, however that led to the
undesirable effect of TASK_IDLE ('I') tasks being sorted above tasks
that were running ('R').
Thus, explicitly recognize the idle process state, and sort it below
others.

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
htopyou can scroll the list vertically and horizontally to see all processes and full command lines. - In
topyou are subject to a delay for each unassigned key you press (especially annoying when multi-key escape sequences are triggered by accident). htopstarts faster (topseems to collect data for a while before displaying anything).- In
htopyou don't need to type the process number to kill a process, intopyou do. - In
htopyou don't need to type the process number or the priority value to renice a process, intopyou do. - In
htopyou can kill multiple processes at once. topis older, hence, more tested.
Compilation instructions
This program is distributed as a standard autotools-based package. See the INSTALL file for detailed instructions.
When compiling from a release tarball, run:
./configure && make
For compiling sources downloaded from the Git repository, run:
./autogen.sh && ./configure && make
By default make install will install into /usr/local, for changing
the path use ./configure --prefix=/some/path.
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.
