sap – Service Access Point specification Description The text2sap and sap2text functions use the format described in this man page. Because all standard ATM tools on Linux use those functions to convert to or from the textual representation of SAP specifications, they expect them in the same format too. The SAP is divided into two…

It is used within the kernel to communicate between various subsystems, though this usage is not documented here, and for…
rtld-audit – auditing API for the dynamic linker Synopsis #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <link.h> Description The GNU dynamic linker (run-time linker) provides an auditing API that allows an application to be notified when various dynamic linking events occur. This API is very similar to the auditing interface provided by the Solaris run-time…
rsocket – RDMA socket API Synopsis #include <rdma/rsocket.h> Description RDMA socket API and protocol Notes Rsockets is a protocol over RDMA that supports a socket-level API for applications. Rsocket APIs are intended to match the behavior of corresponding socket calls, except where noted. Rsocket functions match the name and function signature of socket calls, with…
roff – concepts and history of roff typesetting Description roff is the general name for a set of text formatting programs, known under names like troff, nroff, ditroff, groff, etc. A roff system consists of an extensible text formatting language and a set of programs for printing and converting to other text formats. Unix-like operating…
richaclex – RichACL Examples Description This man-page demonstrates the various features of Rich Access Control Lists (RichACLs) by example, and shows how they interact with the POSIX file permission bits. For a complete description of the structure, concepts, and algorithms involved, please refer to richacl(7). Examples Traditional POSIX file permissions as RichACLs In the traditional…
richacl – Rich Access Control Lists Description Rich Access Control Lists (RichACLs) are an extension of the traditional POSIX file permission model to support NFSv4 Access Control Lists <URL: https://tools.ietf.org/rfc/rfc5661.txt > on local and remote-mounted filesystems. A RichACL can always be translated into an equivalent NFSv4 ACL which grants the same permissions. RichACLs can be…
npm-removal – Cleaning the Slate Synopsis So sad to see you go. sudo npm uninstall npm -g Or, if that fails, get the npm source code, and do: sudo make uninstall More Severe Uninstalling Usually, the above instructions are sufficient. That will remove npm, but leave behind anything you’ve installed. If that doesn’t work, or…
remote-filesystems – event signalling that remote filesystems have been mounted Synopsis local-filesystems [ENV]… Description The remote-filesystems event is generated by the mountall(8) daemon after it has mounted all remote filesystems listed in fstab(5). mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel…
regex – POSIX.2 regular expressions Description Regular expressions ("RE"s), as defined in POSIX.2, come in two forms: modern REs (roughly those of egrep; POSIX.2 calls these "extended" REs) and obsolete REs (roughly those of ed(1); POSIX.2 "basic" REs). Obsolete REs mostly exist for backward compatibility in some old programs; they will be discussed at the…

Synopsis rdrand-gen [–amount NUM] [–method NAME] [–output FILE] [–threads NUM] [–aes-ctr [–aes-keys FILE]] [–verbose] [–version] [–help] Description RdRand is an instruction for returning random numbers from an Intel on-chip hardware random number generator. RdRand is available on Ivy Bridge and later processors. It uses cascade…
rdma_cm – RDMA communication manager. Synopsis #include <rdma/rdma_cma.h> Description Used to establish communication over RDMA transports. Notes The RDMA CM is a communication manager used to setup reliable, connected and unreliable datagram data transfers. It provides an RDMA transport neutral interface for establishing connections. The API concepts are based on sockets, but adapted for queue…
raw – Linux IPv4 raw sockets Synopsis #include <sys/socket.h> #include <netinet/in.h> raw_socket = socket(AF_INET, SOCK_RAW, int protocol); Description Raw sockets allow new IPv4 protocols to be implemented in user space. A raw socket receives or sends the raw datagram not including link level headers. The IPv4 layer generates an IP header when sending a packet…
random – overview of interfaces for obtaining randomness Description The kernel random-number generator relies on entropy gathered from device drivers and other sources of environmental noise to seed a cryptographically secure pseudorandom number generator (CSPRNG). It is designed for security, rather than speed. The following interfaces provide access to output from the kernel CSPRNG: *…
