perl: Parse and execute a Perl statement.

perl

$ perl -e ${perl_statement}

try on your machine

The command "perl -e" is used to run a one-line Perl script directly from the command line. The parameter "${perl_statement}" should contain the Perl code that you want to execute. When you run the command, the Perl interpreter is invoked, and the Perl code specified in "${perl_statement}" is executed. The output or result of the Perl code will be displayed on the command line. For example, if you have the following command: perl -e 'print "Hello, World!\n";' When you run this command, the Perl interpreter will execute the code within the single quotes (in this case, "print "Hello, World!\n";"). The output will be the string "Hello, World!" followed by a new line. It's worth mentioning that any Perl code snippets surrounded by single quotes within the "${perl_statement}" should not contain single quotes, as it may cause issues. If you need to include single quotes within the Perl code, you can escape them using a backslash (). For instance: ``` perl -e 'print "He said, \'Hello, World!\'\n";'
