[SOLVED] Trying to find a maximum from a file in shellscript

Issue

In shellscript, I'm trying to get the maximum value from different lines. There are 5 things in a line, and the fifth is the value, that I need to compare to the others in the lines. If I found, what the maximum is, then I have to write out the rest of the line too.

Any advices how could I do it?

Solution

Sort numerically, by field 5, then print only the line containing the highest value:

sort -nk5,5 data.txt | tail -n 1
