Need help with a shell script
Hi All,

I have wrote the attached shell script for automatically sending email notification to users if an alarm incident has occurred. However it does not integrate the traceroute command as expected. Suppose output of trace2=`head -1 /tmp/.mdev3.txt | cut -f1 -d"|"` is equal to MICRO2000 then traceroute $trace2 should give output as below -
Code:
traceroute to MICRO2000 (3.66.108.35), 30 hops max, 40 byte packets
 1  3.49.6.3 (3.49.6.3)  5.013 ms  5.052 ms  5.133 ms
 2  3.0.4.1 (3.0.4.1)  4.518 ms  4.683 ms  4.760 ms
 3  3.0.4.51 (3.0.4.51)  4.755 ms  4.756 ms  4.772 ms
 4  3.59.1.201 (3.59.1.201)  4.784 ms  4.887 ms  4.890 ms
 5  3.59.1.3 (3.59.1.3)  5.009 ms  4.992 ms  5.145 ms
 6  3.59.10.3 (3.59.10.3)  5.791 ms  5.836 ms  5.670 ms
 7  3.128.12.14 (3.128.12.14)  6.896 ms  6.875 ms  6.687 ms
 8  3.25.92.64 (3.25.92.64)  71.243 ms  71.678 ms  66.761 ms
 9  micro2000 (3.66.108.35)  69.367 ms  65.060 ms  69.706 ms

but it gives me attached error on screen. I have also attached the sample email generated by this script in the zip file.

Moreover, this script picks only first alarm incident. I want it to send email for second, third, fourth and fifth incident as well. This is more important then traceroute.

Please assist me with this.

Regards,
Shashikant Shelke

In your script there is this line:
Code:
traceroute $trace2

The $trace2 is not enclosed in double quotes, so if $trace2 is empty , or when it contains three or more words for example, then you will get the usage message:
Code:
$ traceroute
Usage: traceroute [..]

$ traceroute ""
traceroute: unknown host

It is ksh93, I believe, as it is using:
Code:
while read -p
do [...]

To fill the to list TO_DL
However there seems to be no coprocess in the script,

So where is it getting its input from?

The CC_list is supposedly getting filled throughout this string of commands:
Code:
CC_DL=$(cat /tmp/COG_DL|paste - - - - - - - - - -|sed 's/    / /g')

Does /tmp/COG_DL exist?
What is in it?
Did you write this script yourself?
Has this ever worked?

Further to Scrutinizer and regarding the "traceroute" syntax error.
Hint: The script contains a diagnostic echo of $trace but no diagnostic echo of $trace2. Suggest you add this diagnostic to your script.

Swiping the badges at doors will not unlock the doors till micros come online this is not true, doors may open if the user has previously used his/her badge at the reader connected to this micro and if the micro is still functioning.
Doors might need connected to micros that are down may have to be manually locked/unlocked
Totally off-topic. It might be a good idea to get someone with good English to vet the wording of your email.

My guess.
Code:
If the micro is still functioning, the doors may still open if the user has previously used his/her badge at the reader connected to that micro.
Doors which are connected to micros and which are down may have to be manually locked/unlocked

Back on topic.
The script only ever sends one email because there is a break command just after the mail command which ends the while do ... done loop.
Warning. If you remove the break command the script will probably send an email every 60 seconds (though the sleep 60 is strangely misplaced in the script) for the duration of the incident. This will drive the email recipients nuts.

As Scrutinizer asked. Did you write this script yourself from scratch?
