:: How to delete the last column

Recently I needed to find a way to remove the last column from a text file.The file contains, let's say, something like

aa bb cde
d e f gh

and I needed the new file to look like

aa bb
d e f

A google search only led me to methods of deleting the last column in a file with fixed number of columns, which doesn't apply to my situation, where the number of columns vary from a line to another. So I suppose this is worthposting here.

The command needed is simply

awk '{$NF =""; print }' oldfile > newfile
