How to use result of ls command in mv command?

Question

linux

I'm looking for a way not to use the mouse when renaming files.
This is usually done like this:

ls *.txt
mv somelongfilename.txt shortname.txt

In this case, the file name must be copied, highlighting the output of ls with the mouse.
PS I am aware of the existence of the Tab key. It would be desirable to combine mv and ls in one command.

Answer 1

The file name does not have to be copied at all, it can simply be typed from the keyboard.
And for mass renaming in Linux there is a rename command .
If there is only one file:
mv `ls -1 old_mask` new_name

Answer 2

why do you need ls at all? Write a small bash script and that's it

Answer 3

for i in `ls`;do mv $i 123${i}; done
will add 123 to all files in the directory in the name

Answer 4

I don’t know how much easier this option is, but 100% convenient https://github.com/mooz/percol
