die function

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

Dear all ,
I want to know the working principle of the die function when I give

 
die "Error" ;
[download]

will print Error with some additional information like line no
but when I give

die "Error\n" ;
[download]

it doesn't print that additional information
why this is happening like this !
Please help me out!

This is documented in 'die' in perldoc, If the last element of LIST does not end in a newline, the current script line number and input line number (if any) are also printed, and a newline is supplied. i.e., this is expected and documented, that is why it is happening.	[reply]

I don't know why this is happening, but it's right in the documentation for die `If the last element of LIST does not end in a newline, the current script line number and input line number (if any) are also printed, and a newline is supplied.` [download] cheers, si_lence	[reply] [d/l]
