+ 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.
