mv to file with I ran the following _mv_ command, apparently by mistake using backslashes by mistake instead of slashes. mv 2015-02-02_flyer_ppces.pdf ..\PPCES2015\2015-02-02_flyer_ppces.pdf The output is empty. The file ..\PPCES2015\2015-02-02_flyer_ppces.pdf is not found by _find_ from root. What does actually happen when I do _mv_ with such parameters? Does the file with this name really exist? I use OS X 10.10.2

You should see file with name `..PPCES20152015-02-02_flyer_ppces.pdf` in the directory where the original file `2015-02-02_flyer_ppces.pdf` was.

Backslash char (`'\'`) is escaping character which you use to escape characters with special meaning for bash like `\, ", ', #, $, ` and others. If you use it before regular character like digit or letter it is the same as writing just that digit or letter, i.e. `\P` is same as `P`.
