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

codeblocks

man(1)							     Code::Blocks IDE man page							    man(1)

NAME

       Code::Blocks - The open-source, cross-platform IDE

SYNOPSIS

       codeblocks  [-h]  [-ns] [-d] [--prefix <str>] [-p <str>] [--profile <str>] [--rebuild] [--build] [--target <str>] [--no-batch-window-close]
       [--batch-build-notify] [filename(s)...]

DESCRIPTION

       codeblocks launches the Code::Blocks IDE. Its various command-line arguments are listed below.

OPTIONS

       -h, --help
	       Displays the list of accepted command-line arguments.

       -ns     Do not display a splash screen on startup. The splash screen can be completely disabled in the program's environment options.

       -d      Enable the debugging log.

       --prefix
	       Specify an alternate path for Code::Blocks to find its shared files.

       -p, --profile
	       Set which profile to use. If you set the profile to ask , Code::Blocks will display a list with all the known  profiles	to  choose
	       from.

       --rebuild
	       Start  a batch rebuild (i.e. "clean" and "build") job on the filenames passed as arguments. The filenames can be either projects or
	       workspaces.

       --build Start a batch build (i.e. no "clean") job on the  filenames  passed  as	arguments.   The  filenames  can  be  either  projects	or
	       workspaces.

       --target
	       Specify a single build target to build in the batch build (or rebuild) job.

       --no-batch-window-close
	       When the batch job ends, the log window closes too. This option keeps it open until you manually close it.

       --batch-build-notify
	       Display a message when the batch job finishes.

EXAMPLES

       Batch build myproject.cpp, only the "Debug" target and keep the batch job window open when finished:
       codeblocks --build --target="Debug" --no-batch-window-close myproject.cbp

       Batch rebuild everything in myproject.cpp:
       codeblocks --rebuild myproject.cbp
