Careful:

1) From the above output it it not certain the the directory is in /.

2) And no its not cool to insert -rf into rm by default. Modern linux 
filesystems on modern storage can delete several thousands files a second! So 
if you just wanted to delete a file and you added rm -rf, just cause you 
think you are Linux ubergeek, and then by mistake you gave rm a directory… 
well farewell to your data.


So first think, then only if really necessary use rm -rf or kill -9.
