Truncate long lines in emacs from command line argument

Question

I know the command in the .emacs for long line truncation is:

(setq-default truncate-lines t)

or the keystroke:

M-x <RET> toggle-truncate-lines <RET>

but how do I pass these as parameters launching emacs from the shell?

emacs --eval '(setq-default truncate-lines t)'

Thank you! The quotes make all the difference it seems, I assume without them the shell tries to interpret them as a bash expression rather then a Lisp command passed to emacs?

This parameter didn't enable truncate-line on my end. Something does not allow to enable truncate line by default. @Gilles 'SO- stop being evil'

@alper Maybe something in your init file turns it off? Or maybe you're opening a file in a mode that turns it off? What exact commands are you using? Does it make a difference if you add -q to the command line?

In my init file file, (global-visual-line-mode 1) was the issue, when I removed it, everything is solved.
