I'm learning Perl and came across the symbol $0. I'm not sure what it represents or how it's used in the context of Perl programming. Can someone explain the meaning and purpose of $0 in Perl?

    Variables play a crucial role in programming.

    One such variable is $1. 3. $0 contains the name of the program currently being executed.

    Depending on the operating system, the behavior of $0 can vary.

    On certain operating systems, assigning a new value to $0 may alter the argument area visible to the ps program.

    However, this functionality is not universal across all operating systems.
