Hi..
I'm new to Perl, I have a input file "Data.txt" in the following format.

Db10g029860.2 7
Db10g029860.2 1
Db10g029860.2 2
Db10g029860.2 1
Db10g029860.2 4
Db10g029860.2 2
Db10g029860.2 6
Db10g029860.2 11
Db96g938791.0 5
Db96g938791.0 9
Db96g938791.0 1
Db96g938791.0 3
Db96g938791.0 7
Db04g787390.1 6
Db04g787390.1 5
Db04g787390.1 5
Db04g787390.1 12
.. etc.

I need to find the total for each unique id's.

Output

Db10g029860.2 34
Db96g938791.0 25
Db04g787390.1 28
.. etc..
