oops... to many files and can't clean up...

To delete all the files in a directory, when there are a large number of
files, but dont delete any sub-directories or files in them:

ls | xargs rm # rm will fail on directories, because you did not use
"-r"

Need to be selective:

find . -maxdepth 0 -name "<wildcard>" | xargs rm
# or
find . -maxdepth 0 -name "<wildcard>" -exec rm "{}" ";" # Slower

Done care about subdirectories and the files in them too:

cd ..
rm -r <directory name> # Probably really want "-rf", its quieter, but
more dangerous.

Want to be "quick" about it:

cd ..
mv <directory name> <directory name>.old # "mv" is fast (on the same
file system), "rm" is slow
rm -rf <directory name>.old & # removing in the background, you can now
go do other stuff.
# including creating a new <directory name> and using it.

Good Luck.

Bob.
