Run shell script in WSL with \r\n

Question

I have a Python project which is a bunch of Docker containers and terraform scripts. My workstation is Windows 10 so I have installed Ubuntu in WSL to develop it. The problem I am facing is there are a lot of shell scripts (.sh) that I need to run as the build process. In Git it always checks out the files as Windows style and commit files as Unix Style. As a result, the Ubuntu bash shell does not like these shell scripts and I have to run dos2unix before running a file. Is there a one liner that allows me to run these scripts without modifying them?

Can you fix up whatever git client you are using to preserve line-ends on checkout? One easier option might be to use git on WSL command line (it's what I do). — JNevill, Mar 11 '20 at 14:26

If the scripts don't call another script you could

tr "\r\n" "\n" script.sh | bash

But in the other case I think you need to change your repository config to tell git to don't convert files with .sh extension. Look at this answer https://stackoverflow.com/a/39461324/5032541

If you want to change git configuration to remove auto conversion, take a look on official documentation. But it's a bad idea.

The main problem imo is checking in the wrong file endings into git.

An easy way to fix all shell scripts at once is:

find . -type f -name "*.sh" -exec dos2unix {} \;

It will recursively find all files with the .sh extension and perform dos2unix on it.

I would recommend setting your git repo to checkout linux style rather than windows line endings.

I do a lot of node/docker/linux work but have a windows 10 laptop, this is what I have done.

git config --global core.autocrlf input

See this link for some more details. This way you dont need to continuously run scripts to make sure you have the correct line endings. Also a good thing to do is set you editor to default to linux line endings.
