Running Script made in Visual Studio Code (on windows) on WSL Ubuntu returns "line 2: $'\r': command not found"

Question

When I try to run a script made with Visual Studio Code on Windows in my Ubuntu WSL installation, I get the error:

line 2: $'\r': command not found

I ran into the question below:

How do I fix "$'\r': command not found" errors running Bash scripts in WSL?.

That all makes sense, however is there a way/setting on Visual Studio Code on windows to not have to use the dos2unix utility every time?

Solution

In the bottom-right corner of the window there is an indicator that says CRLF or LF [highlighted in green on the picture] which will let you set the line endings for a particular file. Clicking on the text will allow you to change the line endings as well.

CR is a bytecode for carriage return (from the days of typewriters) and LF similarly, for line feed. It just refers to the bytes that are placed as end-of-line markers.

Sources and references:

• Visual Studio Code: How to show line endings.
• VSC on GitHub: How to replace characters as newline break.
• Difference between CR LF, LF and CR line break types?
