Ques:- How do you you check the return code of a command in perl?
Asked In :-
Right Answer:
You can check the return code of a command in Perl by using the special variable `$?`. After executing a command with backticks or `system`, you can access `$?` to get the return code. For example:
```perl
my $output = `command`;
my $return_code = $? >> 8; # Shift right to get the actual return code
```
Or for `system`:
```perl
my $return_code = system("command");
```
