Hello friends,

I have the following data:

abc-xyz
abc = 0-999
xyz = 0-999

and there are 10000 lines or more:

Example of data file:

123000
123001
123004
123005
123004
123004
123008

I am looking for a script which will count the number of times the same number repeat. My result from the given data above should be:

123000 1

123004 3
123005 1
123008 4
246599 1

246888 1
246999 6
