Section A: File system and Scripting
Mount shows all devices on system
Reasons for not Mounting at Boot time;
• Parameters are incorrect in /etc/fstab
• A corrupted filesystem on /dev/hdc6
• A corrupted hard disk
Commands used to find more information about the nature of the problem;
gksu gedit /etc/fstab
sudo umount /dev/sdb2 # Note it may not be mounted and the command will say
so
sudo mount -a # Attempts to mount all fstab entries. It will complain if one or
more won't work

Section B: Account Management
Simple shell script, which reads a text file called newusers.txt;
#!/bin/ksh
file="/home/John John Smith/newusers.txt"
while IFS= read line
do
# display $line or do something with $line
echo "$line"
done <"$file"
Creates these users on the system without any interactive input
Script;
read usr_nameread usr_group
useradd -g $usr_group -m $usr_name
passwd $usr_name
read usr_nameread usr_group
useradd -g $usr_group -m $usr_name
passwd $usr_name
