In computing, redirection is a form of interprocess communication, and is a function common to most command-line interpreters, including the various Unix shells that can redirect standard streams to user-specified locations. The concept of redirection is quite old, dating back to the earliest operating systems (OS).
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
See Template:Man/die.net for an example; see Template:Man/FreeBSD for a demonstration of varying the attribution by manual section. Internals Template:man handles choosing the default source and calling it for URL and attribution; the default source is Template:man/default , which is a template redirect currently to Template:man/SUS .
In addition to the binary application code, the executables may contain headers and tables with relocation and fixup information as well as various kinds of meta data. Among those formats listed, the ones in most common use are PE (on Microsoft Windows), ELF (on Linux and most other versions of Unix), Mach-O (on macOS and iOS) and MZ (on DOS).
In this case the usual shell syntax is used for the word (“here string syntax”), with the only syntax being the redirection: a here string is an ordinary string used for input redirection, not a special kind of string. A single word need not be quoted: $
m4 is a general-purpose macro processor included in most Unix-like operating systems, and is a component of the POSIX standard. The language was designed by Brian Kernighan and Dennis Ritchie for the original versions of UNIX. It is an extension of an earlier macro processor, m3, written by Ritchie for an unknown AP-3 minicomputer. [1]
Process substitution can also be used to capture output that would normally go to a file, and redirect it to the input of a process. The Bash syntax for writing to a process is >(command). Here is an example using the tee, wc and gzip commands that counts the lines in a file with wc -l and compresses it with gzip in one pass:
A variant of PJW hash had been used to create ElfHash or Elf64 hash that is used in Unix object files with ELF format.. Allen Holub has created a portable version of PJW hash algorithm that had a bug and ended up in several textbooks, as the author of one of these textbooks later admitted.
