substitute chars with some variable value 1

[ns705]

Hi,
I'm very sorry for bothering you with such simple question.
The single excuse is I see Perl program at the first time in my life.
Can you please help me?
I have some file with records looking like:
/directory/subdir/unknowndir/file
I need to change this "unknowndir" with a value of some variable.
That is, with $variable="/newestdir", for example.
I need redo the above line into
/directory/subdir/newestdir/file.

Thank you in advance.
And sorry for bothering once more.

$path = "/directory/subdir/unknowndir/file";
$variable="/newestdir";
$path =~ s|/unknowndir|$variable|;

print "$path";

Kind Regards

Duncan,

thank you a lot!
My problem was also I received that variable as
var=$ENV{USER}
And it didn't work while I changed var="$ENV{USER}"
To tell the truth, I don't quite understand what I have done
Oh, Perl is a real Terra Incognita for me.

Thank you.

that should not matter - for example my $ENV{USER} is currently set to 'Duncan' so:-

$path = "/directory/subdir/unknowndir/file";
$path =~ s|/unknowndir|/$ENV{USER}|;
print "$path";

returns:-

/directory/subdir/Duncan/file


Kind Regards
