making each line double vim
shell, vi, vim
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.
Problem
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?
