12 Practical Examples of Linux Xargs Command for Beginners. Xargs is a great command that reads streams of data from standard input, then generates and executes command lines; meaning it can take output of a command and passes it as argument of another command.
If no command is specified, xargs executes echo by default. You many also instruct it to read data from a file instead of stdin. There are several ways in which xargs is useful in daily usage of the command line. In this article, we will explain 12 practical Linux xargs command examples for beginners. 1. Here, the action command -print0 enables printing of the full file path on the standard output, followed by a null character and -0 xargs flag effectively deals with space in filenames. Multiarch/HOWTO. Translation(s): Brasileiro - English - Español - Français - Русский Multiarch lets you install library packages from multiple architectures on the same machine.
This is useful in various ways, but the most common is installing both 64 and 32-bit software on the same machine and having dependencies correctly resolved automatically. In general you can have libraries of more than one architecture installed together and applications from one architecture or another installed as alternatives. Note that it does not enable multiple architecture versions of applications to be installed simultaneously. Being able to actually *run* the installed packages completely depends on the kernel and possible qemu-user configuration: GNU Parallel.

Bash - Using named pipes. Sometimes you may want to output something by one program and input it into another program, but can't use a standard pipe. ls -l | grep ".log" You could simply write to a temporary file: touch tempFile.txt ls -l > tempFile.txt grep ".log" < tempFile.txt This works fine for most applications, however, nobody will know what tempFile does and someone might remove it if it contains the output of ls -l in that directory.
Read continuously from a named pipe. Named pipes Named Pipes, , but each instance has its own buffers and handles, and provides a separate conduit for client/server communication.
A named pipe is a named, one-way or duplex pipe for communication between the pipe server and one or more pipe clients. All instances of a named pipe share the same pipe name, but each instance has its own buffers and handles, and provides a separate conduit for client/server communication. Named pipe, Both on Windows and POSIX systems, named-pipes provide a way for inter-process communication to occur among processes running on the On Windows, the thing called a "Named pipe" is an IPC object more like a TCP socket - things can flow both ways and there is some metadata (You can obtain the credentials of the thing on the other end etc). Unix named pipes appear as a special file in the filesystem and can be accessed with normal file IO commands including the shell.

Why you should use named pipes on Linux. Named Pipes: FIFOs (Unix Power Tools, 3rd Edition) Using Named Pipes (FIFOs) with Bash. It's hard to write a bash script of much import without using a pipe or two. Named pipes, on the other hand, are much rarer. Like un-named/anonymous pipes, named pipes provide a form of IPC (Inter-Process Communication). With anonymous pipes, there's one reader and one writer, but that's not required with named pipes—any number of readers and writers may use the pipe.
Named pipes are visible in the filesystem and can be read and written just as other files are: Multithreading - How to write to and read from the same named pipe in a single ruby script? Bash - Open terminal and run command, from the command line. Fun with Unix Named Pipes. November 21, 2017.
Introduction to Named Pipes. One of the fundamental features that makes Linux and other Unices useful is the “pipe”.
Pipes allow separate processes to communicate without having been designed explicitly to work together. This allows tools quite narrow in their function to be combined in complex ways. A simple example of using a pipe is the command: ls | grep x When bash examines the command line, it finds the vertical bar character | that separates the two commands. The above, familiar to most Unix users, is an example of an “unnamed pipe”. Linux - Looping through the content of a file in Bash. How to close file descriptor via Linux shell command.
Section 17.4. Passing File Descriptors. 17.4. Passing File Descriptors The ability to pass an open file descriptor between processes is powerful. It can lead to different ways of designing clientserver applications. It allows one process (typically a server) to do everything that is required to open a file (involving such details as translating a network name to a network address, dialing a modem, negotiating locks for the file, etc.) and simply pass back to the calling process a descriptor that can be used with all the I/O functions. All the details involved in opening the file or device are hidden from the client. We must be more specific about what we mean by "passing an open file descriptor" from one process to another. When we pass an open file descriptor from one process to another, we want the passing process and the receiving process to share the same file table entry.

Archivemount: mounts an archive for access as a file system - Linux Man Pages (1) Archivemount: mounts an archive for access as a file system archivemount - mounts an archive for access as a file system archivemount [-hVdfs] [-ooptions] archivepathmountpoint The archivemount command mounts the file tree contained in the archive archivepath on the directory mountpoint. The archive's contents can subsequently be accessed inside mountpoint as a file system. The umount(8) command performs the corresponding unmount operation. archivemount is known to work under both linux and Mac OS X (via MacFUSE).

Internet web infrastructure company Cloudflare announced plans to drop support for Google's reCAPTCHA service and move to a new bot detection provider named hCaptcha. Cloudflare co-founder and CEO Matthew Prince said the move was motivated by Google's future plans to charge for the use of the reCAPTCHA service, which would have "added millions of dollars in annual costs" for his company, costs that Cloudflare would have undoubtedly had to unload on its customers.
"That is entirely within their right," Prince said yesterday. Five Discourses of Matthew. In Christianity, the term Five Discourses of Matthew refers to five specific discourses by Jesus within the Gospel of Matthew. The five discourses are listed as the following: the Sermon on the Mount, the Missionary Discourse, the Parabolic Discourse, the Discourse on the Church, and the Discourse on End Times. Each of the discourses has a shorter parallel in the Gospel of Mark or the Gospel of Luke. Third-party cookies alternatives. CloudFlare Watch. CloudFlare's half-baked SSL: suspicious sockets layer.

Also see this technical analysis (PDF, 545 KB) on the use of SSL by CloudFlare and similar services.
