sort hash based on values

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

Hi All,

I have an hash %hoa like this,

$VAR1 = {
'userid-000003' => [ 'userid-000003', ' Thur sep 15 04:36:48 PDT 2005'
+, ' Running', ' Thur sep 15 04:47:52 PDT 2005' ], 'userid-000002' => 
+[ 'userid-000002', ' Thur sep 15 04:36:48 PDT 2005', ' Running', ' Th
+ur sep 15 04:47:52 PDT 2005' ], 'userid-000001' => [ 'userid-000001',
+ ' Thur sep 15 04:36:48 PDT 2005', ' Running', ' Thur sep 15 04:47:52
+ PDT 2005' ], 'userid-000004' => [ 'userid-000004', ' Thur sep 15 02:
+46:48 PDT 2005', ' Completed', ' Thur sep 15 02:57:52 PDT 2005' ] };

I need to sort this hash based on the values in either of the column.
That is my hash key refers to,
job_id => [job_id, submit_time, status, complete_time].
How could I sort it based on job_id (or) submit_time (or) status (or) complete_time.

Please help me in this.
Senthil

Do you mean generate a sorted array of the hash keys sorted by hash value? See How do I sort a hash (optionally by value instead of key)?. Perl is Huffman encoded by design.	[reply]

yeah rite. get the keys based on the sorted values. i got it now. here it is, `@sort_keys = sort { $hoa{$a}[0] cmp $hoa{$b}[0] } keys %hoa;` [download] Thanks Senthil	[reply] [d/l]

Hi, I can tell you the way how you have to do this. 1) Traverse in Hash. 2) derefrence the value since that is array reference. 3) then sort the array using sort function sort @$value derefrenceing 4) then you do the rest as per your requirement "Keep pouring your ideas"	[reply]
