The date -d option is not working for me...

I want to find the future date i.e. next monday.

Try this function...

#!/usr/bin/ksh

function dayshift {
  perl -e '@f = localtime(time+(86400*$ARGV[0]));
    printf "%04d%02d%02d\n", $f[5]+1900, $f[4]+1, $f[3];' -- $1
}

NEXT_MONDAY=$(dayshift $((8-$(date '+%u'))))

...format is YYYYMMDD, but change the printf if you want.
