urxvt -e
 

Now I'm sure this is something stupid or I'm not understanding what the flag is for, but when I try running urxvt -e "pacman -Su" it seems as if nothing happens. I tried the same with aterm, I see what may be an aterm flicker on the screen for less than half a second and it's gone. Now if I do a plain pacman -Su or urxvt it works fine, where am I going wrong?

I'm doing this from a python script but I get the same results if I type the command straight into a terminal, I want to open a new terminal window that stays open and is running the command I specify.

Thanks :)

not suposed to use the quotes

Both yield the same results as before :(

Any other ideas?

Rxvt requires some command line switches to work properly. Pacman probably complains about either lack of color support (-tn rxvt) or too small terminal size (-geometry 80x25). Try running it in the terminal you started with plain urxvt, it should display an error message.

Nah, it works fine when I run it normally in the terminal. Like I said in the first post, I can run pacman fine and I can run urxvt and get a new terminal window fine, individually it works great, that -e switch is where the problem is though. Maybe it's an issue with my setup or something because it seems to work fine for other people :( Was in IRC getting people to do it and it works for everyone except me, any ideas?
