(Bash scripting)setting variables from the shell

I want to do this (dont give me other ways of doing this specific task since I want to make an abstract to apply in other situations) # locate netscape (pipe) grep xpm (pipe) cp stdout /opt/kde/share/icons Now how do I assign: "locate netscape (pipe) grep xpm" to be variable $1 and then how do I manage to make cp copy $1 ? What about more than a variable? Thanks! Raul
