LAB-1

 

LAB-1) Create a total of 12 files with names tv_seasonX_episodeY.ogg. Replace X with the season number and Y with that season's episode, for two seasons of six episodes each.

LAB-2) As the author of a successful series of mystery novels, your next bestseller's chapters are being edited for publishing. Create a total of eight files with names mystery_chapterX.odf. Replace X with the numbers 1 through 8.

LAB-3) To organize the TV episodes, create two subdirectories named season1 and season2 under the existing Videos directory. Use one command.

LAB-4) Move the appropriate TV episodes into the season subdirectories. Use only two commands,specifying destinations using relative syntax.

LAB-5) To organize the mystery book chapters, create a two-level directory hierarchy with one command. Create my_bestseller under the existing Documents directory, and chapters beneath the new my_bestseller directory.

LAB-6) Using one command, create three more subdirectories directly under the my_bestseller directory. Name these subdirectories editor, plot_change, and vacation. The create parent option is not needed since the my_bestseller parent directory already exists.

LAB-7) Change to the chapters directory. Using the home directory shortcut to specify the source files, move all book chapters into the chapters directory, which is now your current directory. What is the simplest syntax to specify the destination directory?

LAB-8) The first two chapters are sent to the editor for review. To remember to not modify these chapters during the review, move those two chapters only to the editor directory. Use relative syntax starting from the chapters subdirectory.

LAB-9) Chapters 7 and 8 will be written while on vacation. Move the files from chapters to vacation. Use one command without wildcard characters.

LAB-10) With one command, change the working directory to the season 2 TV episodes location, then copy the first episode of the season to the vacation directory.

LAB-11) With one command, change the working directory to vacation, then list its files. Episode 2 is also needed. Return to the season2 directory using the previous working directory shortcut. This will succeed if the last directory change was accomplished with one command. Copy the episode 2 file into vacation. Return to vacation using the shortcut again.

LAB-12) Chapters 5 and 6 may need a plot change. To prevent these changes from modifying original files, copy both files into plot_change. Move up one directory to vacation's parent directory, then use one command from there.

LAB-13) To track changes, make three backups of chapter 5. Change to the plot_change directory. Copy mystery_chapter5.odf as a new file name to include the full date (Year-Mo-Da). Make another copy appending the current timestamp (as the number of seconds since the epoch) to ensure a unique file name. Also make a copy appending the current user ($USER) to the file name. See the solution for the syntax of any you are unsure of (like what arguments to

pass to the date command). Note, we could also make the same backups of the chapter 6 files too.

LAB-14) The plot changes were not successful. Delete the plot_change directory. First, delete all of the files in the plot_change directory. Change directory up one level because the directory cannot be deleted while it is the working directory. Try to delete the directory using the rm command without the recursive option. This attempt should fail. Now use the rmdir command, which will succeed.

LAB-15)  When the vacation is over, the vacation directory is no longer needed. Delete it using the rm command with the recursive option. When finished, return to the home directory.
