dtpstree
shows running processes as a tree. It is a reimplementation of
pstree
from PSmisc for FreeBSD, NetBSD, OpenBSD, DragonFly BSD, and
possibly other modern BSD variants. It also works without /proc
and will show
the full set of processes in a jail even if init
is not present.
It is released under the Apache License, Version 2.0.
You can check out the code straight from the Git repository:
git clone https://git.douglasthrift.net/douglas/dtpstree.git
The code is also available on GitHub if you would like to make a pull request there.
On FreeBSD, you can install it from the port sysutils/dtpstree:
cd /usr/ports/sysutils/dtpstree
make
make install
Or you can use pkg
instead:
pkg install dtpstree
On NetBSD or other systems using pkgsrc, you can install it from the port sysutils/dtpstree:
cd /usr/pkgsrc/sysutils/dtpstree
make
make install
Or, if there is a binary package, you can use pkg_add
instead:
pkg_add dtpstree
On OpenBSD, you can install it from the port sysutils/dtpstree:
cd /usr/ports/sysutils/dtpstree
make
make install
Or you can use pkg_add
instead:
pkg_add dtpstree
On DragonFly BSD, you can install it from the port sysutils/dtpstree:
cd /usr/dports/sysutils/dtpstree
make
make install
Or you can use pkg
instead:
pkg install dtpstree
On Debian GNU/kFreeBSD you can install it apt.douglasthrift.net:
