Let me explain you the problem
$ date +%c -d "$d" Tue 31 Dec 2013 01:13:06 PM CET $ date +'Today is %F' -d "$d" Today is 2013-12-31
This solution corresponds to current date.
But I have one variable which stores date other than current date
$Prev_date="Wed Dec 25 06:35:02 EST 2013"
I am looking for solution to read this date as 2013-12-25 and store it in a variable.
I have tried this:
a=`date --date=$Prev_date '+%y/%m/d'` echo $a
It's giving this error:
date: illegal option -- date=Wed usage: date [-u] mmddHHMM[[cc]yy][.SS] date [-u] [+format] date -a [-]sss[.fff]
