The shebang is incorrect, because the "!" character is missing after the "#".
The way it is right now, it's acting as a shell script comment. I say "shell script" because you are executing it as a shell script due to the way you've invoked it. And so the shell balks at the "(" character.
Several months ago I found a link that explained the difference between how a Unix Systems Admin would do scripting compared to what a Unix Programmer would do.
It showed a basic script and then show several iterations that explained how the Systems Admin would change it to make it better. I was... (0 Replies)

Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSuUser(Contributed Perl DocPerl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr(3pm)NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument "substr" instead of writing "substr($foo, 2, 6) = $bar".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway discourages the use of "substr()" as an lvalue, instead recommending that the 4-argument version of "substr()" be used instead.
substr($something, 1, 2) = $newvalue; # not ok
substr($something, 1, 2, $newvalue); # ok
The four-argument form of "substr()" was introduced in Perl 5.005. This policy does not report violations on code which explicitly
specifies an earlier version of Perl (e.g. "use 5.004;").
CONFIGURATION
This Policy is not configurable except for the standard options.
SEE ALSO
"substr" in perlfunc (or "perldoc -f substr").
"4th argument to substr" in perl5005delta
