OS: Kubuntu 18.04 or Ubuntu 18.04

I want to remove the first seven characters of certain strings I copy. For example, I want to first copy and then convert 

1234567890

to

890

I can do so with the following code:

xsel -b -o | cut -c 8-

I can put the code into a simple script and can run that script successfully in a terminal.

#!/bin/bash
xsel -b -o | cut -c 8-

But that does not help to paste the modified contents into a GUI-based text file . So I assigned keyboard shortcuts to the code directly or to the corresponding script. But either way, nothing happens in Kubuntu 18.04 or in Ubuntu 18.04 when I press the assigned keyboard shortcut.

Even

#!/bin/bash
bash -c 'xsel -b -o | cut -c 8-'

does not work.

Why is that? Is is something peculiar to xsel (and to xclip which poses the same issue)?

This script works when bound to a keyboard shortcut:

#!/bin/bash

xsel -b -o | cut -c 8- | tr -d '\n' | xsel -b -i

After running the script, the trimmed string can be pasted into the destination file using standard paste methods.
