write a shell script to execute a command
Hello all,
I have just started doing shell scripting.
I want to read a file which stores the status of my job I have submitted
on a cluster.
The file looks something like this :
========================FILE=============================

crab: Checking the status of all jobs: please wait
crab:
ID STATUS E_HOST EXE_EXIT_CODE JOB_EXIT_STATUS
--------------------------------------------------------------------------------------------
1 Done
2 Done

crab: 2 Total Jobs
=====================================================

The highlighted lines display the status of the jobs. The status shown is done. Whenever it is done I want to give a command which is "getoutput" to retrieve my jobs.
So I want to write a small script which can read this file and whenever it is
done it just retrieves the output.
Could somebody tell me if there is a way to do this using shell script?

This is something which I tried doing but didnt work. "out" is file which stores the output info

==================================line========================================

flag[1]=0
flag[2]=0
cat out | gawk 'BEGIN{i=1;}{if($2=="Done") { $flag[i]=1; }'

if($flag[1]==1 && $flag[2]==1); then
getoutput
fi
================================================================================

But this doesnt seem to work because it seems that its treating flag[1] & flag[2] as local variables inside
gawk.


Thanks

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
