Pls clarify why we are use minus (-) and plus (+) symbol .. tail and head commands .. ? And usage . 2. If I need 10th line how can write the command 3. Usage of sed command ?
I know this is late, but I thought I should put this here incase anyone else needed this. If you want to see the 10th line you just have to put a head into a tail command like: head -n 10 file_name | tail -n 1 This command gets the first 10 lines using the head command. Then it pipes that into a tail command which takes the last line of the first ten lines, which in the end gives you the tenth line. If you say wanted to get lines 12-15 you could do: head -n 15 file_name | tail -n 4 This command uses the same principle of the last one, but instead of getting just the 15th line, it gets the 15th line and the 3 lines before it (line 14, 13, and 12). Hope this helps someone, somewhere, someday.
