If you need the result without the newline, use substitute() like this: let x = substitute(system("some command"), "\n", "", "")
This will remove all newlines, not just at the end.
No, it will remove the first newline, whether it's at the end or not.
If one knows that command will output newline at the end, then he should just use system(...)[:-2].
Yes. Or if you don't, use "\n$" as the pattern. Slower, but will only catch an end-of-string newline and only if it exists. Ben. -- You received this message from the "vim_use" maillist.
