Check for the correct date format in UNIx
Hi All,
I am getting two input from User for Date from the command prompt when
my script is executed .
The date format i am taking is : DD-MM-YYYY
so is there any method in Unix to validate the two input date.
There might be many cases for these two date to be invalid. Few are :
Date1 is Greater than Date2.
The format of date1 and Date2 is not correct.
The DD can be more than 31.
Similarly for month.
Thanks
