I have been using `ls -Rlh /path/to/directory > file` to create some text file records of what's in some hard drives.

I want to delete some strings from the text files after they've been created.

An example of part of a text file is:

```

-rw-rw-r-- 1 emma emma 512K Oct 31 01:15 a004.jpg
-rw-rw-r-- 1 emma emma 531K Oct 31 01:15 a005.jpg
-rw-rw-r-- 1 emma emma 532K Oct 31 01:15 a006.jpg
-rw-rw-r-- 1 emma emma 400K Oct 31 01:15 a007.jpg
-rw-rw-r-- 1 emma emma 470K Oct 31 01:15 a008.jpg

-rw-rw-r-- 1 emma emma 470K Oct 31 01:15 a010.jpg

```

The actual text files are thousands of lines long and several megabytes in size.

What I want to do is delete everything before the file size from each applicable line, so that each line starts with the file size. E.g.

```
512K Oct 31 01:15 a004.jpg
531K Oct 31 01:15 a005.jpg
532K Oct 31 01:15 a006.jpg
400K Oct 31 01:15 a007.jpg
470K Oct 31 01:15 a008.jpg

```

However, I want to keep all of the other lines (with the directory names and total sizes) intact, so this means that I can't use `colrm` or `cut`.
