Question

In linux, you have file called test.txt, how do you insert line "hello kevin" before line 7 of this file (note: do it so that the output will just be sent to stdout, i.e. the file itself will not be changed)

Answer

sed -e '7i \
hello kevin' test.txt

^^ note: the syntax of using 7i, to insert BEFORE line 7
^^ also note the use of '\' to break the line up properly, although following is totally correct too: sed -e '7i hello kevin' test.txt
