bash script file copied with additional character in filename

Question

I am writing a bash script to copy some config files. I run the file using sudo bash configure.sh.

#!/bin/bash
cp config/ocr_pattern /usr/share/tesseract-ocr/tessdata/ocr_pattern
cp config/ocr_config /usr/share/tesseract-ocr/tessdata/tessconfigs/ocr_config

However when I view the changes made, ocr_config is copied correctly but ocr_pattern is copied with ocr_pattern? as the filename instead of ocr_pattern. There is an additional character ? behind in the filename for ocr_pattern. What is the issue here?

cat -A

#!/bin/bash^M
cp config/ocr_pattern /usr/share/tesseract-ocr/tessdata/ocr_pattern^M
cp config/ocr_config /usr/share/tesseract-ocr/tessdata/tessconfigs/ocr_config

Do you have three periods in your code? If so, you shouldn't — user2182349

I don't understand your question - perhaps you could clarify it a bit — user2182349

You may have a stray trailing character after file1 in your script. — user2182349

Your file may have DOS \r\n line endings. Check with cat -v. — John Kugelman

As shown by the output of cat -A, you have carriage return (\r) at the end of some lines causing the mentioned issues.

Remove those:

sed -i 's/\r$//' configure.sh

or just use dos2unix:

dos2unix configure.sh
