problem with command Set Title field from substring of filename

[groofie]

I'am using Win 11
and exiftool 12.72

The goal is to replace the ImageDescription with a substring of the filename

I searched on google and found

https://exiftool.org/forum/index.php?topic=9922.0
    exiftool "-title<${filename;$_=substr($_,4,3).' '.substr($_,7,5)}" DIR

https://exiftool.org/forum/index.php?topic=4779.0
    "-title<${filename;s/^.{11}(.*)\..*$/$1/}"
    another way (using substr) would have been:
    "-title<${filename;$_=substr($_,11);s/\.[^.]*$//}"

This is my commandprompt in windows

Code Select Expand

D:\__OurProgs\exiftool\exiftool -ImageDescription<${filename;s/^.{11}(.*)\..*$/$1/} -overwrite_original -r -m -F "D:\____Bewerken\Foto"
And also

Code Select Expand

D:\__OurProgs\exiftool\exiftool -ImageDescription<${filename;$_=substr($_,11);s/\.[^.]*$//}" -overwrite_original -r -m -F "D:\____Bewerken\Foto"
But i alway's receive the warning

And All the ImageDescription are replaced by $

I suspect that you are using PowerShell.  Doing some quick tests I see similar output, especially when not quoting the part of the command with the less than sign <. Commands with dollar signs can also cause problems in PowerShell.

Try using CMD and make sure you put quotes around the parts with the less than sign.

D:\__OurProgs\exiftool\exiftool "-ImageDescription<${filename;s/^.{11}(.*)\..*$/$1/}" -overwrite_original -r -m -F "D:\____Bewerken\Foto"

TIL PowerShell doesn't necessarily need quotes around a less/greater than sign in a tag copy operation.

Can you use single quotes in PowerShell to prevent expansion of "$" variables?

Yes, but there are problems depending upon the command.  For example, the second command in this post shows that single quotes are not enough. Something in the -if condition requires escaping.

Here's an example of not needing quotes around a redirection, but adding the braces that would spit out some garbage


I no longer have the patience to figure out PS's idiosyncrasies beyond running a command to verify an error. It's too much of a pain to do so.

Fair enough!

Tx guy's and idd the problem is powershell, stupid of me because in the manual only command prompt is marked.

I used the different proposials and marked the results. What i understand is that with commandprompt i have to use " and with powershell '.

D:\__OurProgs\exiftool\exiftool "-ImageDescription<${filename;$_=substr($_,11);s/\.[^.]*$//}" -overwrite_original -r -m -F "D:\____Bewerken\Foto"

Not stupid at all.  Windows defaults to PowerShell unless you specifically try to run CMD.
