Full Discussion: calling 'n' number of shell scripts based on dependency in one shell script.
Top Forums Shell Programming and Scripting calling 'n' number of shell scripts based on dependency in one shell script. Post 302367864 by frans on Tuesday 3rd of November 2009 04:31:31 PM

In shell it would be something like
Code:
3.1
STATUS=$(FunctionToGetValueFromOracleTable STATUS_TBL STATUS_RUN 3.1)
[ $STATUS = "complete" ] || exit 1 # exit with error
3.2
STATUS=$(FunctionToGetValueFromOracleTable STATUS_TBL STATUS_RUN 3.2)
[ $STATUS = "complete" ] || exit 1 # exit with error
... and so on

maybe better in a loop like
Code:
for PROG in 3.1 3.2 3.3
do
     $PROG
     STATUS=$(FunctionToGetValueFromOracleTable STATUS_TBL STATUS_RUN $PROG)
     [ $STATUS = "complete" ] || exit 1 # exit with error
done

It's a kind of template
Notes :
  1. The script waits the called process to finish, therefore it's not necessary to check "running"
  2. the construction with || replaces the if not [condition] then .. fi
  3. Maybe you need to replace the [ ] with [[ ]]

scsi_start

SCSI_START(8)							     SG3_UTILS							     SCSI_START(8)

NAME

       scsi_start - start one or more SCSI disks

SYNOPSIS

       scsi_start [--help] [--verbose] [--wait] DEVICE [DEVICE]*

DESCRIPTION

       This Bourne shell script calls the sg_start utility on each given DEVICE. The purpose is to spin up (start) each given DEVICE.

OPTIONS

       Arguments to long options are mandatory for short options as well.

       -h, --help
	      print out the usage message then exit.

       -v, --verbose
	      increase level or verbosity.

       -w, --wait
	      wait for the spin up (start) on each given DEVICE to complete.  The default action is to do each start in immediate mode.

NOTES

       If a large number of disks are spun up at the same time (i.e. without the --wait option) then the power supply may be overloaded.

EXIT STATUS

       The  exit  status of this script is 0 when it is successful. Otherwise the exit status is that of the last sg_start utility called. See the
       sg3_utils(8) man page.
