Hi DOn -

Thank you for the replies! I'm operating on a AIX environment.

Since the quarter syntax is whacky, what would you suggest instead? My thoughts are to still utilize the if/elif logic, but instead use month instead. While there would be more conditions using month, it seems safer.

As far as :
FirstQtrWeek : The script should determine if it it the first Saturday of the 1st quarter month. If so, set it. If not, it needs to refer to that week until the next quarter.

& LastQtrWeek,the script should determine if it is the 3rd quarter month of the current quarter, and then determine if it is the last Saturday.

I hope I explained that well enough?

I wrote the quarter derivation portion like this:

Code:
if [[ $(date +%-m) -ge 1 && $(date +%-m) -le 3 ]]
then
    _CH=1
    _PQ=4
    _PQM1=OCT
    _PQM2=NOV
    _PQM3=DEC
    _SVYEARL=$(date +%Y --date="1 year ago")
    _SVYEARS=$(date +%y --date="1 year ago")
elif [[ $(date +%-m) -ge 4 && $(date +%-m) -le 6 ]]
then
    _CH=1
    _PQM1=JAN
    _PQM2=FEB
    _PQM3=MAR
    _SVYEARL=$(date +%Y)
    _SVYEARS=$(date +%y)
    _PQ=$(($(($(date +%-m)/4+1))-1))
elif [[ $(date +%-m) -ge 7 && $(date +%-m) -le 9 ]]
then
    _CH=2
    _PQM1=APR
    _PQM2=MAY
    _PQM3=JUN
    _SVYEARL=$(date +%Y)
    _SVYEARS=$(date +%y)
    _PQ=$(($(($(date +%-m)/4+1))-1))
elif [[ $(date +%-m) -ge 10 && $(date +%-m) -le 12 ]]
then
    _CH=2
    _PQM1=JUL
    _PQM2=AUG
    _PQM3=SEP
    _SVYEARL=$(date +%Y)
    _SVYEARS=$(date +%y)
    _PQ=$(($(($(date +%-m)/4+1))-1))
fi

crashdc

crashdc(8)						      System Manager's Manual							crashdc(8)

NAME

       crashdc - Diagnostic data collection for a running or crashed system

SYNOPSIS

       /usr/bin/crashdc [system-kernel] [core-image]

DESCRIPTION

       The  crashdc  utility  examines	the core image of the operating system to extract critical diagnostic data. This utility is a shell script
       that invokes several tools and commands that extract selected parameters of a running or a crashed system (for example,	system	configura-
       tion, running processes, and panic messages).

       The  arguments  to the crashdc utility are the system kernel and the core image. The default values are /vmunix and /dev/mem, respectively.
       If you specify no arguments, the crashdc utility examines the running system.

       The system usually invokes the crashdc utility during system startup. If the most recent core dump has been saved by the savecore  command,
       both  the  core image and the system kernel (respectively vmcore.n and vmunix.n, where the variable n is the crash number) are saved in the
       crash directory (by default, /var/adm/crash). Also, the crashdc utility saves the output as the file crash-data.n (where the variable n	is
       the  crash number) in the crash directory. The crashdc utility is invoked only if crash-data.n output in the crash directory does not exist
       or is not from the most recent crash.

FILES

       Default core image Default system image Output from crashdc

       Commands: dbx(1), kdbx(8), savecore(8)
