Concatinating paths in bash (.sh) resolves in path with '$'\r''

Question

I get a string from a command that lokos like the following:

part1=$(pip install numpy 2>&1)

part1 has stored some variable like: c:\programdata\anaconda3\lib\site-package

Now I want to append "numpy" to it. To do so I tried it with:

part1+=/numpy

and every other solution listed here: How to concatenate strings in bash

However the output looks like this: 'c:\programdata\anaconda3\lib\site-packages'$'\r''/numpy'

What do I have to do to get rid of this effect?

I am using Windows10 and scripting .sh files.

You can use:

part1="${part1/$'\r'}/numpy"

Here "${part1/$'\r'} replaces \r by an empty string. $'\r' is special bash construct to enter escape sequences.

Thank you that worked, can you may explain what you have done?(I assume it is some kind of regex that deletes the \r part? – Kev1n91 Aug 23 '17 at 11:35
