having problems with index of a date string

[kathyjjja]

Hello everyone,
 
I am trying to add the date to a file name. I finally got rename to work, but 
now I am having problems with indexing the date string. Index works fine on any 
other string, but for some reason it is not seeing the characters in date. Here 
is the code:
 
my $where
my $dateTime = localtime;
print "dateTime = $dateTime\n";
# dateTime looks like this:  Fri Nov 11 14:59:49 2005
$where= index($dateTime, "N");
print "where = $where\n";
 
index() cannot find anything in the $dateTime string. I am thinking that this 
data is actually stored in another format and when you ask for it to be 
printed, it formats it nicely for you automatically. If that is true, how can I 
get a date as a string that I can manipulate?
 
Thanks,
Kathy

Kathy,

 I'm not sure exactly what problem you are having.  When I ran your code below 
(after putting a
semi-colon after `my $where`), I got the result of `where = 4` which is the 
index of the letter N in
the $dateTime string.  What is it you are expecting to see?

Usually when I want to do something like this, it's to make a uniquely
named temp file, so the date doesn't need to be human readable, so
something like this works just fine:

# filename__
my $tmpfile = '/var/tmp/prefix_'. $$ .'_'. time;

Just a thought. Simpler (than having to parse a string-formatted
date), which is always good.

Cheers,
Dave
