Perl equivalent of PHP’s escapeshellarg

by

String::ShellQuote, but most of the time this is not needed. You simply can avoid invoking the shell by careful programming. For example, system takes a list of arguments instead of a string.

Best practice:

use IPC::System::Simple qw(systemx);
systemx($command, @arguments);

require IPC::System::Simple;
use autodie qw(:all);
system([@allowed_exit_values], $command, @arguments);
