{} expands to the current file find is processing. Hence,
find . -ctime +10 -exec rm -f {} \; would execute rm(1) once per file found,
and might cause largeish overheads.
rm -f `find . -ctime +10` might not work if the argv[] array to rm(1)
becomes really large.
Hence, to process large number of files, use xargs.
find . -ctime +10 | xargs rm -f
And the -print0/-0 technique to handle filenames with spaces in them.
Best to put this in a file, chmod +x it, and run that file from cron.
