Just a quick post to help burn this into longer term memory.

Today I was having to check some info in a generated csv file that had a header and footer row. I only wanted the records in between, so I needed to remove the first and last lines of that CSV, after I got the columns I needed.

cut <args> my.csv | tail -n +2 | sed '$d'

The tail -n +2 command starts at the second line and outputs the input stream/file. The sed '$d' command deletes the last line of the file.
