Given that `pro` is not a standard Linux command, a universal synopsis demonstrating its invocation, options, and arguments cannot be provided. Its syntax would be entirely dependent on the specific application or script it belongs to, if it exists at all.

The command `pro` is not a standard or widely recognized utility found in typical Linux distributions or core utility packages. Unlike common commands such as `ls`, `grep`, or `awk`, `pro` does not have a universal manual page entry on most systems, indicating its absence as a default system tool. Its presence usually signifies a highly specialized application, a component of a specific software suite (e.g., the Progress OpenEdge ABL client, where 'pro' launches the client environment), or a custom script developed for a particular environment. It could also be a typo for other standard commands like `ps` (process status) or a reference to concepts like the `/proc` filesystem. Without specific contextual information, a general analysis of `pro` as a universal Linux command is not feasible.

Execution of `pro` on a standard Linux system will almost certainly result in a 'command not found' error. Users encountering `pro` in documentation or scripts should investigate its context thoroughly to determine if it refers to a specific, non-standard application or a custom-defined alias/function. Its behavior and availability are entirely contingent on a non-default software installation.

There is no documented history of `pro` as a widely adopted or standard Linux command within the general Linux ecosystem. Its development and usage would be confined to niche applications or specific proprietary software systems, rather than being part of the common set of Linux utilities.
