So I need to do something like: sudo mv backup/gem/foo gem/ sudo ...

This is a pretty simple question, at least it seems like it should be, about sudo permissions in linux. There are a lot of times when I just want to append something to /etc/hosts or a similar file but end up not being able to because both > and >> are not allowed, even with root. Is there someway to make this work without having to su...
Bash is getting a little long-in-the-tooth. Windows has PowerShell (formerly known as Monad), which is capable of dealing with richer objects than just lines of text. Is there any equivalent new powerful shell for Linux/Mac? It should be of similar expressiveness and functionality to Bash, but not afraid to tackle things in a differ...
I am trying to call a shell script that sets a bunch of environment variables on our server from a mercurial hook. The shell script gets called fine when a new changegroup comes in, but the environment variables aren't carrying over past the call to the shell script.

When you use a standard Windows "file open" dialog using GetOpenFileName(), the shell will load various DLLs that it requires to display the file list, including custom ones. In my application, I found that the DLL that TortoiseCVS uses to draw overlays on the icons was calling GdiPlusShutdown(), and so some time after displaying a "fil...
