$listVar is a diagnostic and debugging function that provides visibility into all currently active temporary variables. Each entry in the output includes both the variable name and its current value.

Output Format

Variables are listed with their names and values in the format name: "value". The default separator is a comma followed by a space: , . To customize this, provide a separator string:

• $listVar[\n] — one variable per line.
• $listVar[ | ] — pipe-separated list.
• $listVar[; ] — semicolon-separated list.

Use \n for a literal newline character in the separator.

Scope

Only temporary variables ($var) are listed. Global and user-scoped variables ($getVar/$setVar) are not included. There is no built-in equivalent for listing persistent variables.

When to Use

• Debugging: verify that variables are set to expected values at various points in a complex command.
• Logging / error messages: include the variable state in error output to help users diagnose issues.
• Dynamic inspection: check which variables exist before branching logic.
