[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 /mntd. 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.txtf. 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
