Could you please try following as a first point and let me know if this helps you.
Code:
cat script.ksh
START_DATE=$1
END_DATE=$2;
if [[ -n $1 && -n $2 ]]
then
awk -vstart_date="$START_DATE" -vend_date="$END_DATE" 'BEGIN{;num=split("JAN FEB MAR APR MAY JUN JULY AUG SEPT OCT NOV DEC", array," ");for(i=1;i<=num;i++){Q[array[i]]=i};split(start_date, A,"-");split(end_date, B,"-");if(A[3] <= B[3] && Q[toupper(A[2])] <= Q[toupper(B[2])]){if((A[3] == B[3] && Q[toupper(A[2])] == Q[toupper(B[2])] && A[1] <= B[1]) || (A[3] == B[3] && Q[toupper(A[2])] < Q[toupper(B[2])]) || (A[3] < B[3] && Q[toupper(A[2])] < Q[toupper(B[2])])){print "start_date " start_date " seems to be less than " end_date " end_date."} else {print "Date is NOT in proper format."}} else {print "Date is NOT in proper format."}}'
else
echo "One of the argument is seems to be missing while running the script."
fi
Examples of some runs as follows.
Code:
./script.ksh 19-MAY-2015 01-May-2015
Date is NOT in proper format.
AND
/script.ksh 19-MAY-2015 31-May-2015
start_date 19-MAY-2015 seems to be less than 31-May-2015 end_date.
It will compare the dates but it is not that intelligent enough if user has given wrong output like 32 days in May month etc(trusting user here ). It will compare the dates and run the script. EDIT: Adding a non-one liner form of solution here too.
Code:
START_DATE=$1
END_DATE=$2;
if [[ -n $1 && -n $2 ]]
then
awk -vstart_date="$START_DATE" -vend_date="$END_DATE" 'BEGIN{
num=split("JAN FEB MAR APR MAY JUN JULY AUG SEPT OCT NOV DEC", array," ");
for(i=1;i<=num;i++){
Q[array[i]]=i
};
split(start_date, A,"-");
split(end_date, B,"-");
if(A[3] <= B[3] && Q[toupper(A[2])] <= Q[toupper(B[2])]){
if((A[3] == B[3] && Q[toupper(A[2])] == Q[toupper(B[2])] && A[1] <= B[1]) || (A[3] == B[3] && Q[toupper(A[2])] < Q[toupper(B[2])]) || (A[3] < B[3] && Q[toupper(A[2])] < Q[toupper(B[2])])){
print "start_date " start_date " seems to be less than " end_date " end_date."
}
else {
print "Date is NOT in proper format."
}
}
else {
print "Date is NOT in proper format."
}
} '
else
echo "One of the argument is seems to be missing while running the script."
fi
