Set Title field from substring of filename?

[jasonkc]

I'm trying this to set the title from the filename starting at the 15 character position:

exiftool -overwrite_original "-title<${filename;$_=substr($_,15);s/\.[^.]*$//}" -ext jpg . 

This give me a "bad substitution" error.

You don't mention what OS you are using. If you're using Mac/Linux, change the double quotes into single quotes, as the double quotes tell the command line that anything with a dollar sign is the start of a shell variable, not part of the exiftool command.

If you're using Windows Powershell, swich to CMD.

Also, as the thread you originally posted in is very old, it didn't use the Basename tag, which removes the need to trim the extension.

Try
exiftool -overwrite_original '-title<${Basename;$_=substr($_,15)}' -ext jpg .

That did the trick! Thank you!
