Wrapping up

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

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.
