cp to copy files to a directory which didn't exist. I have no clue where they went to, and the worst part is it filled up my primary 120gb ssd so I can't make any changes to anything. Where did the copies go, so I may move them?
If you remember any of the files,
sudo find / -name "name of file"
This might take a while.
cp doesn't create directories on its own(it throws and error saying that the destination is not a file or directory), so if at all the files were "copied" to a destination that does not exist, it would mean you have copied to the same folder with a new name.
To figure out the new name which, if you don't remember, you can just do the following on a terminal:
du --apparent-size -h
This will give you the files in your current directory(including the hidden ones), so you can remove the file/directory of 120GB.
However, if you do remember the new name, you could also do a
find as Mr.Lee suggested, but I would recommend you do a
sudo updatedb first and then do a much faster
