I have a file with following data (tab/space separated columns):

Code:

I would like to swap the two columns. I know it is got to be something very simple but can't seem to figure out.

Thanks

Code:

awk '{print$2, $1}' file

awk -F" " '{print $2, $1}' filename > newfilename

(assumes that the column separator is a space)

Edit--beaten to the punch again....
