Awk: Remove everything after the first word in each line

  Another awk question. How to remove everything after the first word in each line? E.g., if we wanted to remove everything but the names in this input (FILENAME.txt):  
Anna 123 09123 Main Street Bob 109 09800 Smith Street Joe 0981 123123 King Street
  We can use awk like so:  
awk ‘{ print $1 }’
  e.g.:  
cat FILENAME.txt | awk ‘{ print $1 }’
  which will print:  
Anna Bob Joe
  Short and sweet.

Awk: Remove first line of file

  Short and sweet – when piping data through awk, how do we remove the first line of the input?  
awk ‘{if (NR!=1) {print}}’
  e.g.  
cat FILENAME.txt | awk ‘{if (NR!=1) {print}}’
  Done!
