A common value is /bin/sh, but some systems such as Solaris have the POSIX-compatible shell at /usr/xpg4/bin/sh. [13] In many Linux systems, /bin/sh is a hard or symbolic link to /bin/bash, the Bourne Again shell (BASH). Using bash-specific syntax while maintaining a shebang pointing to sh is also not portable.

$ # bash shell $ /bin/bash-c 'echo a{p,c,d,b}e' ape ace ade abe $ # A traditional shell does not produce the same output $ /bin/sh-c 'echo a{p,c,d,b}e' a{p,c,d,b}e When brace expansion is combined with wildcards, the braces are expanded first, and then the resulting wildcards are substituted normally.
A software build is the process of converting source code files into standalone software artifact(s) that can be run on a computer, or the result of doing so. [1]In software production, builds optimize software for performance and distribution, packaging into formats such as '.exe'; '.deb'; '.apk'.
Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. [5] The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. [6] It was first released in 2013 and is developed by Docker, Inc. [7]
Podman is a drop-in [19] replacement for Oracle Container Runtime for Docker in Oracle Linux 8 and Oracle Linux 9. Podman, Buildah, and Skopeo are a set of tools that you can use to create, run, and manage applications across Oracle Linux systems by using Open Container Initiative (OCI) compatible containers.
Editing a FreeBSD shell script for configuring ipfirewall. A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. [1] The various dialects of shell scripts are considered to be command languages.
Shell builtins work significantly faster than external programs, because there is no program loading overhead. However, their code is inherently present in the shell, and thus modifying or updating them requires modifications to the shell. Therefore, shell builtins are usually used for simple, almost trivial, functions, such as text output.
Build automation is the practice of building software systems in a relatively unattended fashion. The build is configured to run with minimized or no software developer interaction and without using a developer's personal computer. Build automation encompasses the act of configuring the build system as well the resulting system itself.
