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, and Sed
Prepare Psmisc for compilation:
./configure --prefix=/usr --exec-prefix=""
The meaning of the configure option:
This causes the binaries to be installed in /bin instead of /usr/bin. Because the Psmisc programs are often used in bootscripts, they should be available when the /usr file system is not mounted.
Compile the package:
make
Install the package:
make install
There is no reason for the pstree and pstree.x11 programs to reside in /bin. Therefore, move them to /usr/bin. Also, there is no need for pstree.x11 to exist as a separate program. Make it a symbolic link to pstree instead:
mv /bin/pstree* /usr/bin ln -sf pstree /usr/bin/pstree.x11
By default, Psmisc's pidof program is not installed. This usually is not a problem because it is installed later in the Sysvinit package, which provides a better pidof program. If Sysvinit will not be used for a particular system, 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)
Reports the Process IDs (PIDs) of processes that use the given files or file systems
Kills processes by name; it sends a signal to all processes running any of the given commands
Displays running processes as a tree
Same as pstree, except that it waits for confirmation before exiting
