File Permissions Visualize and Change the File Permissions. a. Navigate to /home/analyst/lab.support.files/scripts/.

[analyst@secOps ~]$ cd lab.support.files/scripts/

b. Use the ls -l command to display file permissions.

[analyst@secOps scripts]$ ls -l

c. The touch command is very simple and useful. It allows for the quick creation of an empty text file. Use the command below to create an empty file in the /mnt directory:

[analyst@secOps scripts]$ touch /mnt/myNewFile.txt
touch: cannot touch '/mnt/myNewFile.txt': Permission denied

[analyst@secOps ~]$ ls -l /mnt
total 4
drwxr-xr-x 2 root root 4096 Mar 3 11:13 second_drive

[analyst@secOps ~]$ ls -ld /mnt
drwxr-xr-x 3 root root 4096 Mar 3 15:43 /mnt

d. The chmod command is used to change the permissions of a file or directory. As before, mount the /dev/sdb1 partition on the /home/analyst/second_drive directory created earlier in this lab:

[analyst@secOps scripts]$ sudo mount /dev/sdb1 ~/second_drive/

e. Change to the second_drive directory and list the contents of it:

[analyst@secOps scripts]$ cd ~/second_drive
[analyst@secOps second_drive]$ ls -l
total 20
drwx------ 2 root root 16384 Mar 3 10:59 lost+found
-rw-r--r-- 1 root root 183 Mar 3 15:42 myFile.txt

f. Use the chmod command to change the permissions of myFile.txt.

[analyst@secOps second_drive]$ sudo chmod 665 myFile.txt
[analyst@secOps second_drive]$ ls -l
total 20
drwx------ 2 root root 16384 Mar 3 10:59 lost+found
-rw-rw-r-x 1 root root 183 Mar 3 15:42 myFile.txt

The chmod command takes permissions in the octal format. In that way, a breakdown of the 665 is as follows: 6 in octal is 110 in binary. Assuming each position of the permissions of a file can be 1 or 0, 110 means rw- (read=1, write=1 and execute=0). Therefore, the chmod 665 myFile.txt command changes the permissions to: Owner: rw- (6 or 110 in octal) Group: rw- (6 or 110 in octal) Other: r-x (5 or 101 in octal) g. The chown command is used to change ownership of a file or directory. Issue the command below to make the analyst user the owner of the myFile.txt:

[analyst@secOps second_drive]$ sudo chown analyst myFile.txt
[sudo] password for analyst:
[analyst@secOps second_drive]$ ls -l
total 20
drwx------ 2 root root 16384 Mar 3 10:59 lost+found
-rw-rw-r-x 1 analyst root 183 Mar 3 15:42 myFile.txt
[analyst@secOps second_drive]$

h. Now that analyst is the file owner, try appending the word ‘test’ to the end of myFile.txt.

[analyst@secOps second_drive]$ echo test >> myFile.txt
[analyst@secOps second_drive]$ cat myFile.txt
