How to generate a range of nonweekend dates using tools available in bash?

I want to generate a list of files where the name consists of ${filename}.${date}, for example file.20111101, file.20120703, starting November 1, 2011 until today and it should exclude weekends.

Thanks.

Solution

  • try this for 2011

    for y in 2011; do
  for m in {1..12}; do
    for d in  `cal -m $m $y|tail -n +3|cut -c 1-15`; do
      printf "file.%04d%02d%02d\n" $y $m $d;
    done;
  done;
done

    or this for NOV-2011 to DEC-2013

    for ym in {2011' '{11,12},{2012..2013}' '{1..12}}; do
  read y m <<<$ym;
  for d in  `cal -m $m $y|tail -n +3|cut -c 1-15`; do
    printf "file.%04d%02d%02d\n" $y $m $d;
  done;
done

    or until end of this month "hard"

    for ym in {2011' '{11,12},2012' '{1..7}};do
  read y m <<<$ym;
  for d in  `cal -m $m $y|tail -n +3|cut -c 1-15`;do
    printf "file.%04d%02d%02d\n" $y $m $d;
  done;
done
