CHALLENGE:

Create the following folder structure inside the existing system folder $/$opt:

$/$opt

$$ enterprise$-$app

$$ bin

$$ code

$$ docs

$$ flags

$$ libs

$$ logs

$$ scripts

Ensure the user root is the owner of the enterprise$-$app folder.

Ensure your regular user account owns all the other folders in the structure except the bin$/$ folder $($which should be owned by the root user$).$

Create the following files:

app.py in the bin folder

stdout.log and stderr.log in the logs folder

README.txt in the docs folder

clean.sh in the scripts folder

pid.info in the flags folder

Set the permissions for the created files as follows:

Anyone can execute the script scripts$/$clean$.$sh$.$

Anyone can read the files inside logs$,$ but they cannot be executed and can only be written by the owner $($your regular account$).$

The file bin$/$app$.$py should have the mode $700.$

Create a symbolic link named alt$\_$app$\_$access under the structure code folder. The link must point to the bin$/$app$.$py file.

Generate a report file with information about two files:

bin$/$app$.$py

scripts$/$clean$.$sh

Extract the information from the two files mentioned above using the stat command as in the following example:

Listing $1.$ Example using the $/$etc$/$passwd File as target:

$ stat $-$c "INODE:$\%$n:$\%$i$"/$etc$/$passwd

INODE:$/$etc$/$passwd:$16948603$

TIP

Look at the stat $--$help$*$

Using redirections save the information in a report file named report.out that must be created inside the docs folder.

The information that must be extracted from the files is the following:

File owner in the format: OWNER::

File octal mode in the format: PERMISSIONS::

File inode number in the format: INODE::

Finally, create the enterprise$\_$app$\_$backup.tar.gz compressed archive file of the $/$opt$/$enterprise$-$app folder structure and files and save it inside the $/$tmp directory.

TIP

You will need the following commands to complete this task:

touch

mkdir

echo

tree

chown

chmod

cat

ls

ln
