Problem: Computer Science
Linux command (ubuntu) after making directory mkdir TEST and cd TEST stuck this problem for following:
You must figure out which Linux command is indicated, review the manual page if necessary, then run the commands in a terminal and capture the output in a log file.
1. In the TEST directory create new folders called A1, A2, and A3.
2. List the folders, then remove the A3 directory and list the folders again to show that it is no longer present.
3. c Change the working directory to A1 and use gedit from the command line to create "test.txt" with the following personal information:
Hello user this is command Linux Bye!
4. Exit gedit and copy the new file "test.txt" to "testBackup.txt". Verify that both files exist by listing the directory.
5. Rename the testBackup.txt file to testOld.txt, then list the directory
6. Remove the testOld.txt file, and list the directory again.
7. List the directory with a long format, then convert the test.txt file to read only. List the directory again to verify the protection has changed.
