1.Please write a Shell script, which could rename the files whose names contain
“eee” in the current directory. “eee”will be replaced by “EEE” in the names of such
files, while the other part of the file names will not be changed. For instance, the file
named “21-eee.doc” will be renamed as “21-EEE.doc”.
2. The file a.txt is about students' information which is as follows:
Tom 10/83 066101 9 male
Jack 03/84 066202 86 male
Lucy 10/84 066103 59 female
Lily 09/85 066114 70 female
Joey 10/85 066103 53 male
Sue 01/84 066003 90 female
Each line includes five items which are student-name, birthday, student- number, score
and sex in sequence.
(1). Sort the lines of a.txt according to the score from high to low
(2). print the number of male student
(3). list the lines whose score are less than 60
(4). Chang the string "male" by "boy", and change the string "female" with "girl",
then saved as b.txt
