# El que abans era: lookupd -flushcache
dscacheutil -flushcache

dscacheutil does various operations against the Directory Service cache including gathering statistics, initiating lookups, inspection, cache flush, etc. This tool replaces most of the functionality of the lookupd tool previously available in the OS.
