bash-3.2$ date +%s

When i try date -d "Filename" +%Y%m%d option it error out saying:-

date: bad conversion
usage:  date [-u] mmddHHMM[[cc]yy][.SS]
        date [-u] [+format]
        date -a [-]sss[.fff]
Solution

  • You can get the date you like with this line of code (bash):

    date +"%Y%m%d"

    you can use it as a filename like this:

    _now=$(date +"%Y%m%d")
_file="/tmp/$_now.ext"

    then use $_file for your filename
