6.49. Psmisc-22.3

The Psmisc package contains programs for displaying information about running processes.

Approximate build time: less than 0.1 SBU
Required disk space: 2.2 MB

6.49.1. Installation of Psmisc

Prepare Psmisc for compilation:

./configure --prefix=/usr --exec-prefix=""

The meaning of the configure options:

--exec-prefix=""

This ensures that the Psmisc binaries will install into /bin instead of /usr/bin. This is the correct location according to the FHS, because some of the Psmisc binaries are used by the LFS-Bootscripts package.

Compile the package:

make

This package does not come with a test suite.

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:

mv -v /bin/pstree* /usr/bin

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 -sv killall /bin/pidof
