Help with Backup Shell Script

Dear friends, I need your help.

I need to create a bash script which can loop through $source_dir once a month, and find the backup of the last day of a given month for each of the 2 file types, as can be seen below.

Assume that source_dir="/backup/daily"
Assume that dest_dir="/backup/monthly"

Assume that the 2 types of files are:
this-file-*.gz
that-doc-*.tar.gz

...as can be seen below.

Type 1:
  • this-file-other-week.gz
  • ............
  • ............
  • this-file-other-day.gz
  • this-file-yesterday.gz
  • this-file-today.gz

Type 2:
  • that-doc-other-week.tar.gz
  • ............
  • ............
  • that-doc-other-day.tar.gz
  • that-doc-yesterday.tar.gz
  • that-doc-today.tar.gz

The script should then pick the 2 files (separately) which have been backed up at the end of the month, and backup each one of them in $dest_dir with such names as:
  • this-file-monthly.gz
  • that-doc-monthly.tar.gz

I am having trouble with this particular component of the script and any help is highly appreciate.

Thank you
