The cut program can be really versatile. Give it the character used to separate columns using the -d switch, and the column(s) you want to print using the -f switch. Here we give ’ ’ as a parameter to the -d switch because spaces indicate the columns here. A single column is given using -fn and multiple columns using -fn,n,n,n,n syntax.
