+# Quick Search for Files
+
+`locate file*`
+
+Locate is fast because it only accesses a database of files which it regularly updates.  You can update this with:
+
+`sudo updatedb`
+
+# Whereis
+
+`whereis angband`
+
+... shows where the angband program is, along with configuration files, and binaries.
+
+Also `which` shows where a binary file is, and `type` shows aliases.
+
+`which cmus`
+
+`type cmus`
+
