cli-sedHow do I delete a line using the CLI sed command?

The sed command can be used to delete a line from a text file. The syntax to delete a line using sed is sed 'Nd'. Here, N is the line number of the line to be deleted. For example, to delete the third line from a text file, the command would be:

$ sed '3d' file.txt

The output of the above command would be the contents of the text file, with the third line deleted.

The parts of the command are:

• sed: the sed command
• '3d': the argument to the sed command, which specifies the line number to delete
• file.txt: the name of the text file to be edited
