−	See [[apropos]]	+	The '''whatis''' command takes a word or name as a parameter value that is searched against a set of database files that contain short descriptions of system based commands and devices.
		+
		+	<pre>
		+	mail# whatis fxp
		+	fxp(4) - Intel EtherExpress PRO/100 Ethernet device driver
		+	</pre>
		+
		+	The search method used by whatis will find only complete word matches. This differs to the related apropos command which uses a search method that matches anything containing the given word. An example of these differences using the word "secure":

		+	'''whatis'''
		+
		+	<pre>
		+	mail# whatis secure
		+	_secure_path(3) - determine if a file appears to be secure
		+	rpc_secure(3) - library routines for secure remote procedure calls
		+	scp(1) - secure copy (remote file copy program)
		+	sftp(1) - secure file transfer program
		+	sprog(7) - secure programming practices
		+	SHA1(3), SHA1_Init(3), SHA1_Update(3), SHA1_Final(3) - Secure Hash Algorithm
