Assuming that you are in hw5 directory

Create a file named work.sh in your hw5 directory	cat > work.sh
Give this file read and write permission (no execute permissions) for you alone. No other account should have any access privileges to this file. Change the permissions on the work.sh file so you have read and write permissions.	chmod u=rw work.sh
Give everybody else, including the group, read permissions only.	chmod go+r work.sh
Give yourself read, write and execute permissions to the file work.sh	chmod u=rwx work.sh
Give everyone else, including the group, execute permissions only.	chmod go+x work.sh
Create a directory named dir1 in your hw5 directory	Mkdir dir1
Give all users, including the group, read, write and execute access to this directory	chmod gou+rwx dir1
Create a directory named dir2 in your hw5 directory	Mkdir dir2
Give yourself read, write and execute permissions on this directory.	chmod u+rwx dir2
Give the group and everyone else only those permissions which will let them run ls on this directory, but nothing else.	chmod go+rx dir2
Create a directory named dir3 in your hw5 directory	mkdir dir3
Give yourself full permissions to this directory.	chmod u+rwx dir3
Give only the group the ability to run ls on this directory	chmod g+rx dir3
Give everyone else no privileges on this directory	chmod o-rwx dir3
