📘 Linux Lab#LI03-2: Manage files

• Create directories for each department (sales, marketing, human resources, IT, engineering) at the root of the filesystem.
• Configure standard Linux permissions and ownership such that each group only has access to its own departmental directories. For example, the sales group has access to the /sales directory but not to other departments’ directories.
  • After completing and testing the previous step, configure ACL permissions to permit the marketing department to have read access to the /sales directory.
  • Use ACL permissions to permit one user account to have read permission to the /IT directory.
  • Configure SGID and the sticky bit on the /marketing directory.
• Ensure that two of your existing user accounts are now members of the marketing group.
  • Use each account to create one file in the /marketing directory.
  • Test whether one of those accounts can delete the file created by the other account (they should not be able to, due to the sticky bit).
• Create a file called unchangeable.txt, set the immutable attribute on it, and then delete the file.
• Configure file links.
  • Create a file named LinksTest.txt in the /opt directory, and then create a hard link to it in the /tmp directory. Use Vim to add a line of text to the file through the /opt/LinksTest.txt path, and then display the file’s contents by using the /tmp/LinksTest.txt file path.
  • Create a symlink to /tmp/LinksTest.txt in the root user’s home directory and view the file’s contents.
  • Delete the /tmp/LinksTest.txt file, and then attempt to view the file’s contents through the /root/LinksTest.txt symlink.
• Create 10 files in the /tmp directory, and then use tar and gzip to bundle and compress the files.
  • Delete the 10 original files and then restore them from your tarball.
• Use the find command to search for the test files in the department directories. Do this task first as the root user, then as a user who is a member of the group that owns the directory, and finally as a user who is not a member of the group that owns the directory.
• At the command line only, practice mounting and unmounting ISO images.
• Copy a file from the ISO to a directory on the Linux installation.
• Configure LVM:
  • Designate two sections of 50MB each of your remaining empty hard disk drive space to be physical volumes (PVs) used by LVM.
  • Combine those to PVs into a single volume group, and then configure a single logical volume (LV) that is 100MB.
  • Create a directory to serve as a mount point for this LV and add an entry to the /etc/fstab so that it is mounted during the system bootup.
