In the world of Linux, effective shell scripting can be a vital skill for anyone from newbies to seasoned system administrators. One of the key concepts when working with bash (Bourne-Again SHell) — the default shell on many Linux distributions — is the use of subshells. Understanding how subshells work and their effect on parent-child process relationships can make your scripts more efficient and prevent common pitfalls. A subshell is a child shell launched by a parent shell command. It inherits a duplicate environment from its parent, allowing it to execute scripts or commands independently.
