     269 ./pinger-20180109.out.gz|gz

Example notes

  • This example makes use of the headtail tool
  • See one of the examples for uniqc for a comprehensive breakdown of the extensions for the same files.

Notes

  • If there is more than one period in a file name, the extension is everything that occurs after the last period.
  • If there are no periods in a file name, it is considered to have no extension and the output line will have a null string for the extension for that file.
  • Extensions are based on the basename of a path. If you have a path such as foo.bar/FOOBAR, the file name has no extension since the period appears in the parent directory of the file.
