Why is there such a performance penalty for using them? Is it appreciable at all in a script which is only 5 or so lines (If you didn't figure it out, the above was just to get the songname of whatever's in XMMS, using xwindow -root -all | grep XMMS_Window.)? Without doing it stupidly (like mine above) or with ubercomplex regex (semi- is fine, I'm still learning) is there a way to get "from the beginning until char"? Muchos Gracias.
