I have written little script to check the CPU performance of the machine.

Request you to contribute your comments on the same.

Feel free to add your own scriptlet to make it better.

I call it as doctortux

I have decided to run the script in two mode

1)Interactive.(Not yet included in script)

2)Automatic.(currently giving CPU information.)

Automatic mode ( -a ) (default):This mode shoudnt ask any input from user and should run automatically.

Interactive mode (-i) : This mode should ask user for input .

What do want to accept from the user in the interactive mode.
From the given title, I assume that the input should be for other devices like hdd, ram etc.

Looks good! You should add a who's logged in option too. Could be useful. Also last few errors in syslog.

I have used w in the script which displays how many terminal connections are established in the machine.

It also gives you who has logged in .

E.g

Code: 
# w

 21:25:51 up  3:38,  1 user,  load average: 1.05, 1.02, 0.94

USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT

root     pts/1    TomcatServer 18:56    0.00s  0.59s  0.00s w

from above output its clear that somebody has taken a terminal from machine (TomcatServer) with root access.

Well there are many ways to include network information. You could parse the information from vnstat or something similar (Need to install, isn't shipped by default). vnStat - a network traffic monitor for Linux and BSD

--- Updated Post - Automerged ---

I m planning to include some content from error file .What is the most common location for checking the error log in system?
 
netstat -a for open ports.

prstat - for process statistics.

iowait - CPU I/O
 
DoctorTux version 1.0 added.

More details are put in following blog.

This is nice! Also other suggestions

- Minor: kernel is spelled kernal in the script

- Security: At the beginning of the script you probably want to define the absolute paths of the commands being used e.g. TPUT = /bin/tput (or wherever the path is). This is to ensure that similarly named malicious files in the current path cannot be run. It's generally a good practice [citation needed] ;-)

- Security: Dissuade the user from running it as root, have a small check that quits if it is running as root.

These are minor quibbles which would be good to have since (I assume) that this script will be continuously developed and more cooler features will be added in future.

Thanks for the useful suggestion.

But i cant implement security feature as you dont get command in same position in different flavors of linux.

By not running the script with root privilege you might end up with some command not running at all.
