The user can search for elements in an associative array, and delete elements from the array. The following shows how multi-dimensional associative arrays can be simulated in standard AWK using concatenation and the built-in string-separator variable SUBSEP:
xargs (short for "extended arguments") [1] is a command on Unix and most Unix-like operating systems used to build and execute commands from standard input.It converts input from standard input into arguments to a command.

On the other hand, the various shells plus tools like awk, sed, grep, and BASIC, Lisp, C and so forth contributed to the Perl programming language. [5] Other shells that may be available on a machine or for download and/or purchase include: Almquist shell (ash) Nushell (nu) PowerShell (msh) Z shell (zsh, a particularly common enhanced KornShell)
String functions common to many languages are listed below, including the different names used. The below list of common functions aims to help programmers find the equivalent function in a language. Note, string concatenation and regular expressions are handled in separate pages. Statements in guillemets (« … ») are optional.
This is a comparison of the features of the type systems and type checking of multiple programming languages.. Brief definitions A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.
The wsl.exe command accesses and manages Linux distributions in WSL via command-line interface (CLI) – for example via Command Prompt or PowerShell. With no arguments it enters the default distribution shell. It can list available distributions, set a default distribution, and uninstall distributions. [30]
Equivalently, awk may be used to print the first five lines in a file: awk 'NR < 6' filename. However, neither sed nor awk were available in early versions of BSD, which were based on Version 6 Unix, and included head. [1]
