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

Answer 1

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
