I think Rscript has a problem running files that have mac encodings

But if I run the file using Rscript on a linux box I get a strange
error message:

I think you are right that Rscript is unhappy to handle files with CR
line terminators. But IIUC, the purpose of Rscript is to enable R
script execution on unix-like systems like:
#!/path/to/Rscript --vanilla
print(1:10)
So then I'm not sure how useful it is for Rscript to handle such
files. Why not convert to a more common and portable line termination
for your R script files?
Notice also that other script interpreters aren't happy about CR line
endings:
$ cat > x.sh
#!/bin/bash
echo hello
Now change the LF to CR and get
$ ./x.sh
bash: ./x.sh: /bin/bash^M: bad interpreter: No such file or directory
or (if you add a space)
$ ./x.sh
echo hello: No such file or directory
$ bash -v ./x.sh
echo hello
(overprinting is involved in the last one).
