Not a standard command.

As 'sr' is not a standard Linux command, there is no universal synopsis. Its usage would depend entirely on its custom definition (e.g., as an alias or a script).

Examples of how 'sr' might be used if defined as an alias:
sr <pattern> <replacement> <file> (if aliased to a search/replace command)
sr <script_path> (if aliased to the 'source' command)

The command 'sr' is not a standard, universally recognized Linux utility found in common distributions. Unlike commands such as ls, grep, or sed, 'sr' does not have a predefined function or a man page within the core Linux system.

Users may encounter 'sr' in various non-standard contexts:
- Custom Aliases or Functions: It is frequently defined by individual users or system administrators as a shortcut (an alias) for more complex commands, often related to 'search and replace' operations (e.g., aliased to sed or grep -r) or to 'source' a script.
- Script Names: 'sr' might be the name of a custom shell script (e.g., sr.sh) created for a specific task.
- Typographical Error: It could be a typo for similar-looking standard commands like strace, sort, or sed -r.
- Niche Tools: In rare cases, 'sr' might refer to a command from a highly specialized, non-standard package (e.g., related to specific hardware tools or embedded systems), which is not part of the common Linux userland.

Therefore, the behavior of 'sr' is entirely dependent on how it has been defined or if it's a specific, obscure utility installed on a particular system. Without such a definition, executing 'sr' will typically result in a 'command not found' error.

Command Not Found: By default, on most Linux systems, 'sr' will not be recognized as a command and will result in an error message indicating it cannot be found.

Context-Dependent Behavior: If 'sr' is defined (e.g., via an alias in .bashrc or .zshrc, or as a script in the user's PATH), its functionality, options, and arguments are entirely determined by that custom definition. There is no shared understanding of what 'sr' does across different Linux environments.

To determine if 'sr' is defined on your system, you can use the type command:
type sr
This command will show if 'sr' is an alias, a function, a built-in, or a file in your PATH. If it's not defined, it will report 'sr not found'.

The command 'sr' does not have a documented history as a standalone, standard Linux command. It has not been part of the GNU Core Utilities or other foundational Linux projects. Its 'history' in Linux usage primarily revolves around its informal adoption as a common abbreviation or alias in personal shell configurations for various 'search and replace' or 'source' operations, reflecting users' desire for shorter, more convenient command shortcuts.
