+Example 10 : Show the method of listing only directories in systems programming
+
+ ****************************************************************
+
+ Answer :
+
+ INSTRUCTIONS :
+
+ 1.These programs are part of systems programming in Unix and the commands have NO EQUIVALENT IN SCILAB
+
+ 2.However if possible some selected programmes have been TRIED TO BE IMPLEMENTED
+
+ 3.For most of the programmes whose equivalent is NOT THERE IN SCILAB,only the output has been printed as given in the textbook w
+ ith no interactive input as in the programme below
+
+ 4.However the .c files which are displayed here are also made into a seperate file.If you are a unix user then try compiling and
+ running the programme with gcc or cc compiler
+
+ 5.The inconvenience is regretted.
