AWK Word count example

We probably all know the wc unix executable which counts:

• number of lines
• number of words
• number of bytes of a given file

We'are going to cover (similar) functionality with small awk program word-count.awk.

Basic example word-count

$ ps auxww > /tmp/ps.log

$ wc  /tmp/ps.log
  389  4737 37752 /tmp/ps.log

$ gawk -f word-count.awk  /tmp/ps.log
  389  4737  37752 /tmp/ps.log

Notes

• This minimalistic word count example suffers from couple of problems, find at least three of them!
