I need to extract the current date and use it in my output file name. How do I convert:
current_date =” 2-Apr-18”
to a fix length, zero-filled date string: cDate=“02-Apr-18”?
(Not an issue when the days of the month are higher than 10.)
I could remove the space:
DEF SYM cDate=($current_date)
PPL SET cdate $EDIT(cDate,compress)
to get cdate="2-Apr-18" but I'd like to have the zero-filled date:
RSS has released a new version (v2) of the CCMP wind product, consistently analyzed from Jul 1987 through May 2016 (http://www.remss.com/
measurements/ccmp). As far as I can tell, this is only available from them, and only by ftp-ing the individual daily files.
The whole global, 28-year fields are more than 285Gb. I want to write a script that will loop through the 10563 days, make daily averages from the four 6-hr values in each file, select my region of interest, and append that to a much smaller file (then delete the ftp-ed file).
(Yes, I'll probably have to run it in chunks over several nights).
My problem is to generate the filenames, which look like the example below:
It's pretty straightforward to define a daily time axis spanning the CCMP dates, REPEAT-loop on the days, and come up with the year/month/day number needed for the filename (e.g. DAYS1900TOYMDHMS). But can anyone sugest a simple way to construct the filename given the need to have leading zeroes for months before October and days of the month less than 10?
I am wishing for the equivalent to TAX_DATESTRING that would produce, e.g., 19910825 instead of 25-AUG-1991.
