Synopsis

V [pkg [vars]]

Displays all (or some) variables in package pkg using a data pretty-printer (which displays keys and their values for hashes, makes control characters printable, prints nested data structures in a legible fashion, and so on). pkg defaults to the main package. Make sure you enter the identifiers without a type specifier such as $ or @, like this:

V DB filename line

In place of a variable name, you can use ~ pattern or ! pattern to print existing variables with names that either match or don’t match the specified regular expression.
