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 \, ", ', #, $, <space> 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.
ls -a, you should find a file..PPCE.....pdf.
