Issue

I want to delete one or more specific line numbers from a file. How would I do this using sed?

Solution

If you want to delete lines from 5 through 10 and line 12th:

sed -e '5,10d;12d' file

This will print the results to the screen. If you want to save the results to the same file:

sed -i.bak -e '5,10d;12d' file

This will store the unmodified file as file.bak, and delete the given lines.

Note: Line numbers start at 1. The first line of the file is 1, not 0.
