/Courseware).(1) Exercise 11th, using Vi/vim/gedit or another editor, write the shell script ex1.sh, which reads as follows:The function of this script is to back up normal files that have been modified within the current directory for the last 1 days (that is, 24 hours). Use the backup system's current datetime as the file name and compress the archive. The error message is written to Error_info during the backup. Then view the backup document and the error message separately.2nd, try the four

are directly using the Student class's private member, age, rather than using its public interface Student.getage (), so they all break object-oriented encapsulation rules, violate interfaces, and implement object-oriented laws that should be separated.
All queries are not native to 100%.
Since there are so many problems, why not just use a purely object-oriented database? Some developers may say: "It lacks the support of mathematical models and is not mature enough". It is true that
