Multiple Pipes (shell scripting)

[spacecoyote]

I have a script which starts out with:

ls -lhagG | grep ^d
ls -lhagG | grep ^-

but I would like to be able to do something like this:

ls -lhagG ls's output to grep ^d and then ls's output to grep ^-

so I don't have to run ls twice. I can't find a howto I can understand. I think what I need to use is named pipes but I'm not sure.

For now I'm using the "write to a file in /tmp/" method...it works pretty good.

Ok...I figured it out. You have to make everything that accesses that pipe run at the same time with &.

Kind of obvious now that I think about it :)

To clarify, the solution was:

ls -lhagG | grep ^d & grep ^-
