Bash Reference Manual Edition 5.0 For Bash Version 5 May 2019

Check your bash version : $bash --version What is Bash? Bash is the shell, or command language interpreter, for the gnu operating system. The name is an acronym for the ‘ Bourne-Again SHell ’, a pun on Stephen Bourne, the author of the direct ancestor of the current Unix shell sh , which appeared in the Seventh Edition Bell Labs Research version of Unix. Bash is largely compatible with sh and incorporates useful features from the Korn shell ksh and the C shell csh . It is intended to be a conformant implementation of the ieee posix Shell and Tools portion of the ieee posix specification ( ieee Standard 1003.1). It offers functional improvements over sh for both interactive and programming use. While the gnu operating system provides other shells, including a version of csh , Bash is the default shell. Like other gnu software, Bash is quite portable. It currently runs on nearly every version of Unix and a few other operating systems − independently-supported ports exist for ms-dos , os/2 , and Windows platforms. source: http://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.pdf changeset Bash 5.0 Released with New Features (Ankush Das) You are here: Home / News / Bash 5.0 Releas
