I find a shell script about awk command in the forum regarding "Find and replace duplicate column values in a row"
In this thread, there is a command line as shown below to replace duplicate
from input
to output
My question is that
1) Can any people explain this part shown above about the awk array? what does v[i,$i]++ mean?
==> if (v[i,$i]++){b[$i]=$i;$i=""}
Thank you so much
Regards,
Eldon
