Read from a file in linux

I have been trying out different solutions to read from a file in linux with no luck at all. My main purpose is to get a http response from an application and store it in a file.

Here is my Code in a shell script file

wget localhost:8080/abc/rest/eventservice/event -O /dev/null -S --quiet 2>&1 | grep "200 OK" > out.txt
while read -r LINE || [[ -n $LINE ]];
do           
    echo "$LINE";
done < out.txt

After i executed the above sh file i get the below error 

'ervercheck.sh: line 6: syntax error near unexpected token `
'ervercheck.sh: line 6: `    done < out.txt

This line wget localhost:8080/abc/rest/eventservice/event -O /dev/null -S --quiet 2>&1 | grep "200 OK" prints HTTP/1.1 200 OK

I have also noticed that when i try to look through the file content and type vi out.txt the content is empty but when i type vi out.txt^M then content is there.

Please help me as why the execution of shell file gives such error and why i have the ^M at end of my file name

It sounds like your script file has windows new lines in it. You can use a shell program dos2unix to convert it or search and replace, this answer has more details.

^M at the end of every line in vim

Update: Since you are using notepad++ in windows, you can also choose the end of line character by going Edit -> EOL Conversion (see Choose newline character in Notepad++). After you've done this you shouldn't have to convert the file every time you copy it over.
