  # Example 4 has used the program "col" for setting tabs as field
# delimiters.  Not bad, but there is another way to do it with the
# stream editor "sed".
who | sed -E 's/ {2,}/\t/g' | cut -f3

# You can compare the results, the way the tabs are set using either
# col or sed, with the following two commands.
who | col | od -a

who | sed -E 's/ {2,}/\t/g' | od -a
