I writing a shell script to parse some file using grep and use the result in subsequent commands.

The relevant part of the source code is

VERSION=`grep "^Stable tag:" readme.md | awk -F' ' '{print $NF}'`
echo $VERSION
echo "Readme file version is $VERSION is it correct"

The relevant line in the readme.md file is

Stable tag: 2.2.2

You would expect a output of 

2.2.2
Readme file version is 2.2.2 is it correct

But I am getting the following as the output

2.2.2
 is it correctrsion is 2.2.2

I am pretty sure there is no (non-printable or non-ascii) character at the end of line in my text file. I checked it by enabling the :set invlist command in vim.

Any idea why it is happening like this? Or any other ideas to debug this issue?

    This looks like a DOS edited file and you working on a Unix like system. Strip the carriage return (Ctrl-M).

    You could use tr(1) to remove those:

    VERSION=`grep "^Stable tag:" readme.md | tr -d '\015' | awk -F' ' '{print $NF}'`

    Awk probably also has some builtin feature to work on these but I do not know awk enough for this.
