{"product_id":"9789888381272","title":"Bash 4.3 Reference Manual","description":"This manual is the definitive reference for GNU Bash. Bash is a command processor that typically runs in a text window, where the user types commands that cause actions. Bash can also read commands from a file, called a script. Like all Unix shells, it supports filename globbing (wildcard matching), piping, here documents, command substitution, variables and control structures for condition-testing and iteration. The keywords, syntax and other basic features of the language were all copied from sh. Other features, e.g., history, were copied from csh and ksh. Bash is a POSIX shell, but with a number of extensions.","brand":"Samurai Media Limited","offers":[{"title":"Default Title","offer_id":47065755025648,"sku":"9789888381272","price":19.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9789888381272_p0.jpg?v=1763693328","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9789888381272","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
