%general-entities; ]> Psmisc 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 Installed programs fuser, killall, pstree and pstree.x11 (link to pstree) fuser fuser reports the PIDs of processes that use the given files or file systems. killall killall kills processes by name. It sends a signal to all processes running any of the given commands. pstree pstree displays running processes as a tree. pstree.x11 pstree.x11 same as pstree except that it waits for confirmation before exiting.
