how do i convert user input (which i assume the example below is as string ) to unix date format?
echo "please enter date [dd/mm/yy]:
I can't use date -d option as my unix is sun solaris n does not support that.
It only supports
date [-u] mmddHHMM[[cc]yy][.SS]
date [-u] [+format]
date -a [-]sss[.fff]
