Difference between find, locate and whereis linux commands find: finds files by filename. see Linux: Search for a File by Filename for more details and example usages. locate: also finds files by filename but does not search the directory structure itself but only a database prepared by updatedb. Because of that locate is faster than find but less accurate. Examples: locate firefox # -> /etc/firefox # /etc/firefox-3.0 # /etc/firefox-3.5 # /etc/alternatives/firefox-homepage # /etc/alternatives/firefox-homepage-locales # [ .

My adsense link unit coverage is low. A lot lower than the coverage for the other adsense ad units so I tried to figure out what is going on. Google has this to say: For link units, coverage reflects the number of link units that showed ads after the user clicked on a term in the link unit. Coverage for pages displaying link units is typically much lower than for the other kinds of ad units, because it involves user clicking.
