Hi, many thanks for your reply! That prints the max value in column 2 for the specific name in column 3, but not the minimum value in column 1. I'll have a play and see if I can get that to work. One solution that was provided elsewhere was, which works perfectly is:
Code:
#!/bin/bash
awk '{
if ( larr[$3] == "" ) {
larr[$3] = $1
harr[$3] = $2
}
if ( larr[$3] != "" ) {
if ( larr[$3] >= $1 ) { larr[$3] = $1 }
if ( harr[$3] <= $2 ) { harr[$3] = $2 }
}
}
END { for (x in larr)
print larr[x], harr[x],x
}' infile > outfile
