How to configure CPAN automatically?

szabgab has asked for the wisdom of the Perl Monks concerning the following question:

When on a newly compiled perl I try to run cpan it asks me if I want to automatically configure it. The thing is that I would like to eliminate even this question, just run the code and let it auto-configure itself. I tried yes | cpan but it got into an endless loop of

Refusing to autoload 'y' in recursion
cpan[40953]> 
Refusing to autoload 'y' in recursion
cpan[40954]> 
Refusing to autoload 'y' in recursion
cpan[40955]>
[download]

Please, don't point me to cpanminus. I specifically need the cpan command.

Provide a configuration for CPAN to use :) citrusperl does it citrusperl\vendor\lib\CPAN/Config.pm ... its just a hash Not sure, but IIRC, Module::AutoInstall does a forced cpan config without prompting (not sure), so see what it does https://metacpan.org/source/BINGOS/Module-Install-1.14/lib/Module/AutoInstall.pm `# last ditch attempt, this -will- configure CPAN, very sorry _load_cpan(1); # force initialize even though it's already loaded` [download] Something https://metacpan.org/pod/CPAN::FirstTime old stuff (i'd stick to hash) Read more...

This ought to do it but it doesn't quite work for me , ignores the first arg, prompts for url list `require CPAN::FirstTime; CPAN::FirstTime::init( 'GonerConfig.pm', autoconfig => 1 , );` [download]	[reply] [d/l]

If you want multiple Enters, you can give the `yes` command a parameter of '' empty string. `yes ''\|cpan` If you want just one Enter — as `cpan` only requires the first one to begin automatically deciding on the remainder of the prompts, you can just pipe in an `echo`. `echo\|cpan` Alternatively, if you feed an empty pipe in, that also seems to work. `cpan < /dev/null`	[reply] [d/l] [select]
