Can't speak for rename. Try to execute with the -x (xtrace) option set.

How about

Code:
find -name $'*\r*' | while read FN; do echo mv "$FN" "${FN%?}"; done

That didnt work RudiC:

FileName:
Code:
FDBCFEAE-021F-47BC-896B-A225C198C1A1{52730124-EF33-405F-9A8A-C840F5CEFB95}0?

Command and result:

Code:
find -name $'*\r*' | while read FN; do echo mv "$FN" "${FN%?}"; done
 ./FDBCFEAE-021F-47BC-896B-A225C198C1A1{52730124-EF33-405F-9A8A-C840F5CEFB95}0}0

No change to the file.

That echo is for check / debug purposes; it displays what the commands had looked like when executed. I should have mentioned that. As you can see in the output, the <CR> (\r) character makes the target file name overwrite the mv command.

- pipe above through less for checking.
- Remove the echo and rerun.

Please try below command. It renames all files in directory/subdirectories.


Code:
 find . -type f -name "*?" | while read file; do mv "$file" "${file%?}"; done

Hi Chandan,

Unfortunately, it removes the last character from the file, no matter what it is, not just the carraige return.

Hi RubiC, that worked a treat, thank you for your help, and your patience as I tried to explain the issue!
