Hi, thanks for that - it sort of works, but only seems to find the first repeat. For example if my file looks like: TRHF 0 KJKF 0 DFJE 0 DJFE 0 KSLR 0 SKJR 0 HGDF 0 TRHF 0 KJKF 0 it will remove the second 'TRHF 0' but stop there and leave all the other repeats. Any ideas? I'm quite new to perl so be gentle!
