To wrap up, you will build a pipeline to find out how many records are in the shortest of the seasonal data files.

Instructions 1/3

undefined XP
  • 1

    Use wc with appropriate parameters to list the number of lines in all of the seasonal data files. (Use a wildcard for the filenames instead of typing them all in by hand.)

  • 2

    Add another command to the previous one using a pipe to remove the line containing the word "total".

  • 3

    Add two more stages to the pipeline that use sort -n and head -n 1 to find the file containing the fewest lines.
