Assignment CS2750 # 2
Advanced Programming in Unix Due Date: September 25, 2007
Unix shell scripts
Create a directory username.2 in your home where username is your user name on admiral. Keep all programs and datales for this assignment in this directory. After you are done with the assignment, remove the object les and executables, and execute the following command: % cd % bhatias/bin/handin cs2750 2 Submit all the code and any data les on a hard copy in class. Write the code in Korn shell. Use the machine admiral.
1. Write a script to give me a list of all les in a directory hierarchy sorted by size. This implies that you should give me just the le names, and not the complete path, for all les in the specied directory as well as the subdirectories underneath. If there are any les with size zero, ask the user whether to delete those les absolute (giving path name for the le), and delete them if the user says yes. The script should allow for directories to be specied as command line parameters, and use the current directory as default if no directory is specied on the command line. The script should be named flcln. 2. Write a script to help me organize all my books in a computer. I want to enter a list of books with the following information: Booktitle: Author(s): Publisher: Year of publication: Each item is to be kept in the le that will be simply called books. The script itself will be called bookinfo. Check for the optional argument and if it is a number, allow me to enter as many books. If the argument is print, print the entire list of books to the printer specied as default. If there is no default printer specied, ask the user to specify the destination printer.
