Try this.
sed -n 's/^\([^ ]*[ ]\).*$/\1/pw xxx.tmp' temp.txt
It is assumed that "temp.txt" is the input file.
This will create a file xxx.tmp with the required data.
This will save a step of creating and later deleting files.
Of course, CUT will be most simplest, but as suggested above see the man command. Should not take more than 5 minutes.
