How do I move files and directories to the parent folder in Linux?

I came here because I'm new to this subject as well. For some reason the above didn't do the trick for me. What I did to move all files from a dir to its parent dir was:

cd to/the/dir
mv * ../

find . -maxdepth 1 -exec mv {} .. \;

this will move hidden files as well.

You will get the message:

mv: cannot move `.' to `../.': Device or resource busy

when it tries to move . (current directory) but that won't cause any harm.

Type this in the shell:

mv *.* ..

That moves ALL the files one level up.

The character * is a wildcard. So *.deb will move all the .deb files, and Zeitgeist.* will move Zeitgeist.avi and Zeitgeist.srt one folder up, since, of course, .. indicates the parent directory.

To move everything including folders, etc, just use * instead of *.*
