- A symbolic link is also known as a soft link and is depicted by an @ symbol appearingat the beginning of the filename when viewed using the ls –l command. True or False?• Exercise 1: Please create a script that print “Hello, your name.” • Exercise 2: Please create a directory call user_bin, and add it to PATH. Then mv script of Exercise 1 to user_bin. Then run it from your root directory.• Exercise 3: Add a new command call ‘l’ which will perform exact same as ‘ls -a’. • Exercise 4: Create a function call sortFile, which will sort all filenames of current directory.• Exercise 5: Please make your own page using shell script, print following as your page. <html><head><title>My System Information</title></head><body><h1>My System Information</h1></body></html> Exercise 6: Could you add one variable in the example, name the variable as greeting, which displays “Hello, my name is xxx xxx” in the body using variable greeting.• Exercise 7: Could you add one variable in the example, name the variable as FILE_LIST, which displays the filenames of current working directoryWrite the command that can be used to perform the following:a.
