I'm moving a file to a different folder and would like to add some kind of index to the newly moved file if a file with the same name exists already (the old one should remain untouched). For example, if `file.pdf` existed I would prefer something like `file1.pdf` or `file_1.pdf` for the next file with the same name.

[Here](https://serverfault.com/questions/267255/mv-rename-if-exists) I've found a variant for the opposite idea — but I don't want to make a "backup".

Does `mv` have some parameters out of the box for that scenario? I use Ubuntu Linux.
