Why should one use a module to get the PID and the PPID of a process where there are the $$ variable and the "getppid()" builtin ? (Not mentioning the equivalent "POSIX::getpid()" and "POSIX::getppid()" functions.) In fact, this is useful on Linux, w...

The /proc/PID/smaps files in modern linuxes provides very detailed information about a processes memory consumption. It particularly includes a way to estimate the effect of copy-on-write. This module implements a Perl interface. The content of the s...

This module reads and writes /proc/[pid]/maps files that contain listed mapped memory regions....

Linux::Proc::Mounts parses the information about mount points provided by the Linux kernel at "/proc/$PID/mountinfo"....

This trivial module provides interface to the Linux setns system call. It also provides the CLONE_* constants that are used to specify which kind of namespace you are entering. Also a new CLONE_ALL constat is provided so you can join/switch to any ty...

This module exposes the linux clone(2), unshare(2) and related syscalls to Perl. $retval = unshare $flags The following CLONE_ flag values (without CLONE_ prefix) are supported for unshare, if found, in this release. See the documentation for unshare...

The linux prctl function allows you to control specific characteristics of a process' behaviour. Usage of the function is fairly messy though, due to limitations in C and linux. This module provides a nice non-messy interface. Most of the text in thi...

This module provides an interface to the Linux DVB API. It is a straightforward translation of the C API. You should read the Linux DVB API description to make any sense of this module. It can be found here: http://www.linuxtv.org/docs/dvbapi/dvbapi....

Pidfile handling to help processes avoid running multiple times....

This module provides information similar to the Unix command 'fuser' about which processes have a particular file open. The way that this works is highly unlikely to work on any other OS other than Linux and even then it may not work on other than 2....

The fanotify API is a filesystem monitoring interface in the Linux kernel. It is intended to be used by file scanners such as virus and malware scanners or file indexers. fanotify has been part of the Linux kernel since 2.6.37 (but needs to be enable...

Linux::CPUAffinity is a wrapper module for Linux system call sched_getaffinity(2) and sched_setaffinity(2). This module is only available on GNU/Linux....

Linux::DVB::DVBT is a package that provides an object interface to any installed Freeview tuner cards fitted to a Linux PC. The package supports initial set up (i.e. frequency scanning), searching for the latest electronic program guide (EPG), and se...

$device can be an open file handle, a device file name, a device number (0, 1, 2..) or empty ("undef"), in which case /dev/rtc is used. The Linux driver has built-in locking so that only one process can have the /dev/rtc interface open at a time. You...

This class returns the Linux memory stats from /proc/$pid/statm....
