Bash: select a column from a file

If for example, you have a file with columns separated by spaces and you want to select a column of data from there, say number 9. This is easy to do in shell using the cut command (note that fields are indexed starting from 1):

cut -d" " -f9 file_list.txt > file_list1.txt
