Hi Don,

I will explain it in a better way. Linux is the operating system and using bash shell.

So the requirement is as below:

We have a script called testit_tas.sh to test the servers which don't get terminated and we pass CTRL+C to kill it everytime. Below is the content of the script:

Code:
!#/bin/bash

./ctftestdump 10.240.56.1 8100 querytas.txt

So when we run this script (./testit_tas.sh) we get this below output on the terminal and it don't get completed. So we kill it manually
Code:
[sasahu@cts-pro-mgmt-srv1 idc_test_tool]$ ./testit_tas.sh
./testit_tas.sh: line 1: !#/bin/bash: No such file or directory
Level Zero : trying to connect/close host 10.240.56.1 at port 8100...
in connect
out connect

5026=1|5001=0<ETX>
5022=QueryTas|4=205|5=E:SHFIN|5045=1|5026=1008|5001=-46<ETX>
5022=QueryTas|4=824|5=E:AASB-ME|5045=1|5026=1007|5001=-46<ETX>
5022=QueryTas|4=216|5=E:2INVE|5045=1|5026=1009|5001=-46<ETX>
5001=-203|5026=1003<ETX>
5001=-203|5026=1004<ETX>
5001=-203|5026=1005<ETX>
5001=-203|5026=1010<ETX>
5001=-203|5026=1011<ETX>
^C[sasahu@cts-pro-mgmt-srv1 idc_test_tool]$

So from above output, we need to search the lines for 5001=-46<ETX> and capture these lines. -46 is error. So we want to capture this and alert only these lines over email to specific people.

Once this script is written, we will schedule it in crontab which will run 3 times to do this check.

Also, I know that to abort the script we can find the process id and kill it but am not sure how to include this.

TIA.

Regards,
Sambit
