cli-sedHow do I use sed to insert a new line in a command line interface?
Sed (stream editor) is a command line utility used to perform text transformations. It can be used to insert a new line in a command line interface (CLI).
For example, to insert a new line after the string "Hello World" in a text file called "test.txt", the following command can be used:
sed -i 's/Hello World/Hello World\n/' test.txt
The command above will produce the following output:
Hello World
The command consists of the following parts:
sed
: The command to invoke the sed utility-i
: The option to edit the file in places/Hello World/Hello World\n/
: The substitution command to replace the string "Hello World" with the string "Hello World" followed by a new line character (\n
)test.txt
: The file to edit
For more information, see the GNU Sed Manual.
