+Syntax
+
+basename string [ suffix ]
+
+Description
+The basename command deletes any prefix ending in ``/'' and the suffix (if present in string) from string, and prints the result on the standard output. The result is the ``base'' name of the file, that is, the filename without any preceding directory path and without an extension. It is used inside substitution marks (` `) in shell procedures to construct new filenames.
+
+Note that the suffix is not deleted if it is identical to the resulting basename.
+
+The related command dirname deletes the last level from string and prints the resulting path on the standard output.
+Exit values
+basename returns the following values:
+
+0
+    successful completion
+
+>0
+    an error occurred 
+
+Examples
+The following command displays the filename memos on the standard output:
+
+basename /usr/johnh/memos.old .old
+
+The following shell procedure, when invoked with the argument /usr/src/cmd/cat.c, compiles the named file and moves the output to a file named cat in the current directory:
+
+   cc $1
+   mv a.out `basename $1 .c`
