Specification and use of Linux System Change Logger Script
As there are numerous commands are used inside the shell script and some of those of
requires elevated privileges than a simple user (i.e. requires root or super user privileges). As
in most of the cases the default root account is locked under some of the Linux distribution.
Therefore, it is suggested to use the ‘sudo’ command in order to execute the script as super
user in the Linux environment. Through the use of the sudo, the kernel of the system allows a
simple user to execute a script or command as a super user.
As by default the Linux does not provide the execute permission for any file in its file
system or a recently created file. Therefore, in order to execute the file it is suggested that,
use of the chmod command in order to provide execute command. Therefore, in order to get
the permission, the following command needs to be executed.
chmod +x mySysMonitor.sh
In the next step, the script can be executed using the following command;
sudo ./ mySysMonitor.sh
Design consideration for the Script
As the script will be responsible for the monitoring the health of the linux based
computers thus the main objective will be to find out the memory, processor and other
resource usage. In addition to that the detail of the users, their home directories, usage of
files, different processes, statics of the usage and users, network interfaces and status of those
interfaces, plugged in devices to the system and finally list all the current processes. System
resource utilization is dependent on the administrator of the system as well as administrator’s
expectation and finally specifications. Only way to determine in case of any unusual
