in reply to basic doubt

Hello vis29, and welcome to the Monastery!

The code shown applies the regex to whatever string is currently stored in the default variable $_, and if the regex matches it assigns the string "not recognized" to the scalar variable $uname.

The regex says:

I’m guessing that the code doesn’t do (anything like) what was intended, but without seeing the surrounding context it’s hard to say exactly what that was. Here is one guess:

$uname = "not recognized" unless exists $hash{server};

Hope that helps,
