+.II "command^find path"
+The command
+.B path
+finds the directory path to a command, if it is in one of the
+directories in your shell's
+.B PATH
+environment variable.
+.PP
+A path means two things in COHERENT:
+.IP \fB1.\fR 0.3i
+It means the list of nested directories within which a file is located.
+For example, file
+.B FOO
+may have the path of
+.BR /usr/local/src/ ;
+this means that FOO
+is kept in directory
+.BR src ,
+which in turn is in directory
+.BR local ,
+which in turn is in directory
+.BR usr ,
+which in turn is in directory
+.BR / .
+.IP \fB2.\fR
+It means a list of directories that the shell searches
+to find an executable program that matches the command typed in.
+Each user has his path stored in the environmental variable
+.BR PATH ;
+to see your path, type the command:
+.DM
+	echo $PATH
+.DE
+.PP
+.B path
+searches the directories named in your
+.B PATH
+to find the path of
+.IR command .
+If
+.B path
+cannot find
+.I command
+or if
+.I command
+is not executable, it returns nothing.
+.SH Example
+If you type:
+.DM
+	path column
+.DE
+.PP
+If this command returns
+.DM
+	/usr/rdb/bin
+.DE
+.PP
+then
+.B column
+lives in directory:
+.BR /usr/rdb/bin .
+.PP
+Please note that for
+.B path
+to work, you must insert into your
+.B PATH
+the directory that holds the
+.B /rdb
+commands.
