Definition: "DCMs" are a command line tool used for running shell scripts on Linux servers. The term comes from "directory command", which refers to a command that moves files recursively from one directory to another within a file system, or in other words, it is used to find and copy files. The word DCM stands for "command and data management." In this context, it refers specifically to managing the commands executed by the shell script. These commands are typically run as part of an elevated user command line interface (CLI) session that runs a bash-like shell or other programming language environment. For example, a simple shell script in bash could look like this: ```bash #!/bin/bash dir="path/to/directory" find "$dir" -type f -exec chmod +x {} \; ``` In this example, the script is running commands that change the ownership of files within a given directory. The term "DCM" comes from the fact that it can be used to manage the command line interface (CLI) session by running elevated user commands.
