The warning message you're seeing, "perl: warning: Please check that your locale settings", indicates that there may be an issue with the locale settings on your system when running a Perl script.

Here are steps you can take to address this issue:

1. Set Locale Environment Variables: You can set the locale environment variables in your shell or in your Perl script itself. Open your script and add the following lines at the beginning:

   Perl

If you want to set it in your shell, you can do it like this:

• export LC_ALL=en_US.UTF-8 # Replace 'en_US.UTF-8' with your desired locale

• Generate Locale: If the locale you're trying to use is not generated on your system, you'll need to generate it. Use the following command to generate a locale:

  bash
• sudo locale-gen en_US.UTF-8 # Replace 'en_US.UTF-8' with your desired locale

• Update Locale Configuration: After generating the locale, you may need to update the locale configuration. This can usually be done in the /etc/locale.gen file. Uncomment the line for the desired locale and then run:

  bash
• sudo locale-gen

• Restart or Re-login: If you've set the locale in your shell, you may need to restart your shell or re-login for the changes to take effect.

• Check Available Locales: You can list the available locales on your system with the command:

  bash
• locale -a

  Make sure that the locale you've set is in the list.

• Verify Locale Settings in Perl: You can print out the current locale settings in Perl using the following code:

  Perl

6. use POSIX qw(locale_h); print "Current locale: ", setlocale(LC_ALL), "\n";

   This will show you the current locale setting used by Perl.

If you continue to experience issues, it's possible that there may be a system-specific configuration that's causing the problem. In such cases, consider seeking further assistance from a system administrator or support channels specific to your operating system.
