Hello, I'm writing a script and I need to create a loop that will execute same commands until file does contain a specified number of duplicate entries. For example, with each loop I will echo random string to file results. And I want loop to stop when there are 10 lines of of the same string.

I thought of something like

while [ `some command here (maybe using uniq)` -lt 10 ]
do
command1
command2
command3
done

Do you have any idea how can this problem be solved? Using grep can't be done since I don't know what string I need to look for.

Thank you for your suggestions.

I have an ArrayList. Contacts is a VO class that has multiple members - name, regions, id. There are duplicates… >>> More
