Linux – Rename images by date with correct time

You can use exiftool. For some reason the online manual does not contain the "RENAMING EXAMPLES" section which gave me the essential hint.

For JPG only files the following command invocation should do the job:

exiftool -r '-FileName<CreateDate' -d '%Y-%m-%d/%H_%M_%S%%-c.%%le' <yourFolder>

Explanation:

• -r is for recursion
• '-FileName<CreateDate' tells exiftool to rename the file accordingly to its EXIF tag CreateDate (you can try others like ModifyDate though)
• -d '%Y-%m-%d/%H_%M_%S%%-c.%%le' tells how to build the filename string from the date source "CreateDate" (the "%-c" will append a counter in case of file collisions, the "%le" stands for "lower cased file extension")
• Note: I used "-FileName<..." here for renaming the files and moving it to another folder within one step. The manual points out that you have to use the "-Directory<..." syntax for folder operations. It worked for me this way though.

You should spend some time reading the manual of this powerful tool. Maybe there is an even shorter way :D

Try this in Powershell:

Get-ChildItem *.jpg | Rename-Item -newname {$_.LastWriteTime.toString("dd.MM.yyyy.HH.mm") + ".jpg"}
