This seemed to work but I noticed that there seem to be a few duplicated left behind. How does the array know what the delimiter? $3 is the field, but not clear on delimiter. Would the same work with tabs for delimiter?
I have a file which looks like
AA BB CC DD EE FF GG HH KK
AA BB GG HH KK FF CC DD EE
AA BB CC DD EE UU VV XX ZZ
AA BB VV XX ZZ UU CC DD EE
....
I want the script to give me only one line based on duplicate contents:
AA BB CC DD EE FF GG HH KK
AA BB CC DD EE UU VV XX ZZ (7 Replies)
