Shell Script to continuously scan a log file
Hello members,

I have some doubts on how to write a script that can reports success / failure of a batch job ?

1. Run a batch job:

2. Wait and search for a particular string in the Log file:
Code:
tail -f log01*.txt | egrep -v "^SUCCESSFUL" 
   echo "continue with the other tasks"
   elsif
     tail -f log01*.txt | egrep -v "^FAILURE"
   echo "Process failed!!"

My questions are :
1. My batch job is likely to create a couple of logs with of type log01*.txt. How do I ensure the script scans through each of those logs to find either of the strings? I'm assuming the '*' can help me with this.

2. Do I continuously scan the log file ( that might still be in the "generation" state ) or wait until the logfile is created completely and then scan for a string ? In this case, how does the script detect that a particular log file has generated successfully, so that it can search for a string ?

Regards

Kris

qrun

qrun(8B)								PBS								  qrun(8B)

NAME

       qrun - run a pbs batch job

SYNOPSIS

       qrun [-a] [-H host] job_identifier ...

DESCRIPTION

       The  qrun  command is used to force a batch server to initiate the execution of a batch job.  The job is run regardless of scheduling posi-
       tion, resource requirements, or state.

       In order to execute qrun, the user must have PBS Operation or Manager privilege.

OPTIONS

       -a	      Specifies the job(s) is to be run asynchronously.

       -H host	      Specifies the host within the cluster on which the job(s) are to be run.	The host argument is the name of a host that is  a
		      member  of  the  cluster	of hosts managed by the server.  If the option is not specified, the server will select the "worst
		      possible" host on which to execute the job.

OPERANDS

       The qrun command accepts one or more job_identifier operands of the form:
	   sequence_number[.server_name][@server]

STANDARD ERROR

       The qrun command will write a diagnostic message to standard error for each error occurrence.

EXIT STATUS

       Upon successful processing of all the operands presented to the qrun command, the exit status will be a value of zero.

       If the qrun command fails to process any operand, the command exits with a value greater than zero.

SEE ALSO
