Re: File::Find and $_ in the wanted sub

[chuckbutler]

in reply to File::Find and $_ in the wanted sub

Localizing $_ is an option, also:

#!/usr/bin/perl

use File::Find;

#find (\&testy, ".");
$_ = 'Main Line...';
testy ('i am a nice parameter');

print "$_\n";

sub testy {

local $_ = shift;  #Localizing it is cool, also.....

print "$_\n" ;

}

__END__

~Output~~
i am a nice parameter
Main Line...

Good luck. -c

PS: The first parameter passed to a sub is in the first element of the list @_, $_[0], which is NOT the same a $_.

I used for since for and local *_ are more thorough than local $_. One problem case:

for ($tied) {
   ...
   local $_ = 'i am a nice parameter';
   testy();
   ...
}

No problem:

for ($tied) {
   ...
   local *_;
   $_ = 'i am a nice parameter';
   testy();
   ...
}

No problem:

for ($tied) {
   ...
   testy() for 'i am a nice parameter';
   ...
}
