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
