Step by step
Solved in 2 steps
- Write the command that will create a tar archive of all the files in the directory named"/fir/sec/thi", that exists on the local machine. The name of the tar archive is "/tmp/animal".The command should be executed from the directory /home/user1. Write the command that will extract the tar archive that was created in Question #63. The contentsof the archive should be placed in the directory "/two/four/six". The command should be executedwhile the current directory is /tmp.A company has implemented a discretionary access control system for important documents and programs on a shared Linux server. Figure 1 shows the current implementation of the DAC system. It only applies to the directory /opt/company (you can ignore all files/directories that are not within this directory). The list of users is shown in the output from the firstls command; the members of each group is shown in the output of the tail command; the permissions are shown in the output of the second ls command. Assume the files are the objects, the subjects are the five users and there are four access rights: own, read, write and execute. Refer to Figure 4.2 and Table 2 in the textbook and complete the following subquestions I. Draw the Access Control Lists that illustrate the implementation on the Linux server; II. Draw the Capability Lists that illustrate the implementation on the Linux server; III. Build the Authorization Table that illustrate the implementation on the Linux server.What does . in a pathname represent? In which type of pathname does it normally specified?

- Imagine you are in your practice directory. Imagine you have a subdirectory there called permDir. In octal mode, recursively change the permissions on all files and directories under permDir to be the following: user: read, write, and execute group: read, write others: none What command/options would you use to recursively change permissions? What command/options would you use to recursively check to see that you were successful?Note that the above numbers might be different in your machine. Bonus You will receive 2% course marks, if you also print the statistics for permission bits as well. Here is sample expected outputs:Assume that you are trying to delete a directory [temp) using the command rmdir but you have received a failed message indicating that the directory not empty. Which command from the following you would execute to accomplish the task? 1 out of O a. rm -a question O b. m -r temp Oc mrdir -r temp Od im p temp
- unix Read the description at the end of Part I that shows the relationship between directory content, inode table and file content before doing this question. Change your working directory to your login directory Create the file called share using cat command under your login directory. Enter one or two lines of text in it. Display the content of the share file Display the number of hard links to the share file ONLY using the long option Using echo command, answer how many hard links (hard link count) the share file has. Display the inode number for the share file using appropriate option. Create the subdirectory, linkdir under your login directory Change working directory to Stay in this directory until the rest of this question. Create a hard link called share2 to the share Remember that the share file is the parent directory and NOT in the current working directory. Hence, you need to specify correct relative or absolute pathname for share file in your hard link command.…UNIX Write a command to copy a directory structure dir1 to dir2?
