Comparing 2 arrays/files

[Larshg]

Hi

I have 2 arrays (or files) and I need to find those names that are i BOTH arrays/files
ex.
array1 contains: name1 name2

array2 contains: name2 name3

The output I need is "name2"

I tryede to find a command like diff, to get the things that are not different - but I can't find an option that will give me that.

Thanks
Larshg

Hi Larshg,
what is the structure of your files ?
Only one line with two or more names ?
A lot of lines with two nimes ?
