Some Ruby scripts from my local git repository:
- exif_date.rb set JPG date/time to the time the picture was taken - from EXIF metadata. Needs exifr gem.
- getopts.rb by Yasuo OHBA has been deprecated and removed from ruby, but I like its simplicity and have many scripts which depend on it
- md5sum.rb calc MD5 sum of a file. Under Windows there is also
fciv -md5(orfciv -sha1or-both)
To be continued.
