Wrench Running a script using another script

Hi ,

I just want to run a script automatically whenever i receive an error called " application failed " .
so i wrote the below script for that , but it is not working .

Code:
#!/bin/ksh 
 
DATE=`date +%Y%m%d` 
 
sanity > /home/sanity_logs_$DATE 
 
if [ "$(grep -c 'Application  Failed' /home/sanity_logs_$DATE)" -eq 0 ]  ; then 
 
  echo "False Alarm  "| mailx -s "False alarm" abc@gmail.com 
  rm -f /home/sanity_logs_$DATE 
else 
  { echo 7; while [1]; do echo c;done;} | start_up
  echo " Failure resolved 
         Below are the processes running 
         $(sanity) " | mailx -s " Failure resolved " abc@gmail.com 
fi

Where "sanity" is the script which monitors the application and " start_up " is the script to start the application.

Once start_up script starts executing first it will ask to select the option " 7" and then it will ask to select the option "c" (many number of times).

please help in me . It is Solaris 5.8 o.s so yes command is not working .

Thank you

If your script prematurely exits, then how will the clean up part run?
You should look at the trap event and create a trap event for exit.
Then if the script errors out, the trap event gets called and can run.

It can be as simple as this. You will need to check the syntax and make
sure that it works under a variety of circumstances.

Code:
#!/bin/ksh 

run_exit_function () {
if [ "$(grep -c 'Application  Failed' /home/sanity_logs_$DATE)" -eq 0 ]  ; then 
 
  echo "False Alarm  "| mailx -s "False alarm" abc@gmail.com 
  rm -f /home/sanity_logs_$DATE 
else 
  { echo 7; while [1]; do echo c;done;} | start_up
  echo " Failure resolved 
         Below are the processes running 
         $(sanity) " | mailx -s " Failure resolved " abc@gmail.com 
fi
}
 
trap 'run_exit_function' exit

DATE=`date +%Y%m%d` 
 
sanity > /home/sanity_logs_$DATE

When i ran my script it is not taking option 7 automatically .. once the script runs it is displaying the prompt with 1 to 10 options.

How the script will take option 7 automatically .

Code:
{ echo 7; while [1]; do echo c;done;} | start_up

Any idea ?

Have a read of:
Run a command for specific amount of time with an auto key press

Or here-doc:
Code:
script.sh << EO_SCRIPT
7
EO_SCRIPT

Hi Sea ,

Thanks for your replay.

But my requirement is to enter multiple inputs . First i need to enter 7 and then i need to enter "c" so may times . so i used while loop as YES command is not working in my O.S.
This is the flow. first i will give 7 as input (only once)and then "c" as input(nearly 30 times) . But the below command is not working ,it is asking for the option 7 to enter .
Can anyone help in this . Any small mistakes like spaces or changing brackets ?/

Code:
{ echo 7; while [1]; do echo c;done;} | start_up

# 6  
Try while true; ... or while : ; .... Don't forget the space just in front of the closing brace.
# 7  
Code:
while [ 1 ]

instead of
Code:
while [1]

would also work.
