How do you execute system commands in Perl?

You can use the system function or backtick operator to call system commands in Perl. Here is an example code for both methods:

1. – structure

my $command = 'ls -l';
system($command);

In the previous example, we used the system function to call the ls -l command to list the files and folders in the current directory.

1. Call system commands using backtick operators.

my $command_output = `ls -l`;
print $command_output;

In the example above, we invoked the ls -l command using the backtick operator and stored the output in the $command_output variable, then printed the output.
