I'm trying to understand a Perl script I encountered, and I came across the symbol $/ which I'm not familiar with. Could someone explain the meaning and usage of $/ in Perl?
The mnemonic for understanding the functionality of the current line number in many programs is that a DOT (.) is often used to represent it.

The input record separator, denoted by $, serves a crucial role in text processing. By default, it is set to newline, meaning that each line is considered a separate record.

Similar to awk's RS variable, the input record separator can be customized. For instance, if it is set to the null string, blank lines will be treated as delimiters between records.

This flexibility allows for the input record separator to be configured to match multi-character delimiters. This can be particularly useful when processing text with specific patterns that span multiple characters.
