making each line double vim

I have a file which looks like this:

file1
file2
file3
.
.
.
filen

I want to convert it to :

echo "file1"
cat file1
echo "file2"
cat file2
.
.
.
.
echo "filen"
cat filen

One way can be to have a for loop and read the content of original file and write modified content to another file , I did that and it worked. Is there any command to do the same in vim through :g or any other command?

Solution

  • Try this:

    :%s/.*/echo "\0"\rcat \0/g

    Explanation:

    :%s/a/b/g means search whole file and replace a to b.

    .* means match every thing in one line.

    \0 means the matched thing.

    \r means the new line.
