Bash file utilities

A series of bash file utilities for users who want to organize simple files (such as photos) without buying a subscription to a premium file utility app.

Place the desired .sh file in the same folder as the files you wish to change, then execute in terminal: sh <filename.sh>

CleanupMediaFileExtensions.sh

• Converts undesirable image extensions (.jpg, .jpeg, .bmp, .heic, .webp) to .png.
• Converts .m4a to .mp3.
• Converts .mov to .mp4.
• This simple script can be altered to include any file extension conversion that you wish!

RenameFileNameByCreatedDate.sh

• Rename a file to its CreatedDate.
• Ex: iOS IMG_0000 filename pattern for photos becomes yyyyMMdd_NNNN.
• The extension of the original file is preserved.

SetCreateDateAndModifiedDateByFileName.sh

• The reverse of the RenameFileNameByCreatedDate.sh script above.
• If a file is already named according to a yyyyMMdd date pattern, this script will set a file's CreateDate and ModifiedDate to reflect the filename. Includes hours-minutes.

StripExifDataAndResetModifiedDate.sh

• Requires imagemagick.org commandline tool for mogrify command.
• Requires files to be named according to yyyyMMdd pattern.
• Preserves the original filename.
• Strips EXIF data (which is a useful for photos).
• Resets the ModifiedDate to be the same month-day-year date as the CreatedDate. Resets hours-minutes-seconds to 00:00:00.
  • The use case for this is to avoid the unfortunate tendency of some file organization programs, such as Apple's Photos app, to prefer arranging files according to their ModifiedDate regardless of the CreatedDate.
