# Description
Fixes#10300 , where using variables didnt work with `ucp` as it was
only expecting a `Expr::FilePath`.
Before: (from the issue)
```
❯ ucp -r $var $folder
Error: × Missing file operand
╭─[entry #40:1:1]
1 │ ucp -r $var $folder
· ─┬─
· ╰── Missing file operand
╰────
help: Please provide source and destination paths
```
Now:
```
`ucp -r $var $folder`
# success
```
Also added the test to ensure its working:) . Oh, and I tweaked again
slightly the messages on two tests because now the whole `path` is
printed rather than `a`. Say:
```
#before
`cp a a` --> 'a' and 'a' are the same file
# now
`cp a a` --> /home/current/location/a and /home/current/location/a are the same file
```
