$array[$i] =~ s/<unknown>/unknown/g;

$array[$i] =~ s/<unknown>/unknown/g;

$array[$i] =~ s/<unknown>/unknown/g;

Can someone explain me what this means? I know how to make a substitution but is this a particular case? In the text there's no the word "unknown" and it seems strange to have "<unknown>".
Thank you !

RE: $array[$i] =~ s/<unknown>/unknown/g;

In what context is it used?

Only a guess but could it be simply to format a text file which has been created and may contain the phrase <unknown> but the output needs to be plain text?


RE: $array[$i] =~ s/<unknown>/unknown/g;

Maybe the <> characters were not escaped?
