BASH Syntax error near unexpected token 'done'

Question

Any idea of what the problem could be?

My code is:

#!/bin/bash
while :
do
echo "Press [CTRL+C] to stop.."
sleep 1
done

Saved it as .sh and ran bash file.sh

CentOS 6 32-bit

What is the issue? First time EVER using BASH, need it for a simple infinite loop on something.

Answer 1

Run cat -v file.sh.

You most likely have a carriage return or no-break space in your file. cat -v will show them as ^M and M-BM- or M- respectively. It will similarly show any other strange characters you might have gotten into your file.

Remove the Windows line breaks with

tr -d '
' < file.sh > fixedfile.sh
