Question

I am just learning to work with csv files from the command line. I want to delete several lines from a file using sed. I’ve removed the header of a file with this cat file.csv | sed 1,2d > file.csv.

Now I want to delete several more lines from the file (lines 3, 10, 12, and 28-35) and I am not sure how to pull it off. I’d be grateful for any help.

Depending on the sed implementation, you could separate them as follows:

cat file.csv | sed "1,2d;10d;12d;28,35d" > file2.csv
