The Psmisc package contains programs for displaying information on processes.
Approximate build time: 0.1 SBU Required disk space: 2.2 MB
Psmisc installation depends on: Bash, Binutils, Coreutils, Diffutils, GCC, Gettext, Glibc, Grep, Make, Ncurses, Sed.
Prepare Psmisc for compilation:
./configure --prefix=/usr --exec-prefix=/
The meaning of the configure option:
--exec-prefix=/: This causes the binaries to be installed in /bin instead of /usr/bin. As the Psmisc programs are often used in bootscripts, they should be available also when the /usr file system isn't mounted.
Compile the package:
make
Now install it:
make install
There is no reason for the pstree and pstree.x11 programs to reside in /bin. We therefore move them to /usr/bin. Also, there is no need for pstree.x11 to exist as a separate program. We therefore make it a symbolic link to pstree:
mv /bin/pstree* /usr/bin ln -sf pstree /usr/bin/pstree.x11
By default Psmisc's pidof program isn't installed. Generally, this isn't a problem because we later install the Sysvinit package, which provides a better pidof program. But if you're not going to use Sysvinit, you should complete the installation of Psmisc by creating the following symlink:
ln -s killall /bin/pidof
fuser reports the PIDs of processes that use the given files or file systems.
killall kills processes by name. It sends a signal to all processes running any of the given commands.
pstree displays running processes as a tree.
pstree.x11 same as pstree except that it waits for confirmation before exiting.
