List files with path using Windows command line
My folder structure in a drive is like this (in Windows): This arrangement continues for 100s of folders. Inside Fd1 of each Folder x there are certain files.

Hardware: Dell Dimension 4500S : i845G, Pentium 4, stock + 2GB RAM and latest (circa 2002) BIOS update. I've been building a Linux system from source, so far it's LFS 7.0 by the book.

Sometimes when I take a picture of a rectangular object, it comes out rotated by a small number of degrees (less than 5 or so). I can make the space where the rectangle isn't white or whatever, but how can I select a non-rectangular (in the sense that it does not line up with the four ninety degree…
Robocopy does not copy the root folder and its time stamp
Robocopy does not copy the root folder and its time stamp - it copies all subdirectories and files (when the appropriate options are set) and there seems to be no option/argument to tell Robocopy you want the root folder itself and its time stamp or attributes to be copied verbatim also. So say I w…

I was browsing the web with Chrome and pressed f. A search box appeared. I then pressed s, after which Chrome asked if I wanted to save the web page.

Custom Commands in ZSH
I'm fairly new to Zsh and Bash. I wish to set up custom commands, for example which would bring me to my desktop. Adding the following lines to the .bash_profile file would work With Bash.

Filenames too long and Windows can't open the files

Good, lightweight GUI-based process monitor for Linux
I'd like a snappy GUI-based (I insist since people still want to propose console-based) application that can show me running processes and allow me to kill them, on Linux. It doesn't need to be as powerful as Window's Process Explorer or even Win7's Task Manager. Is there something lightweight and …
"Open file with" dialog upon startup?
Every time I login to my PC, I receive this message: Now, it's not that big of a deal, and Windows 7 works just fine. What's odd is that it's supposedly just a generic 'Program' that 7 is trying to open. It's done this since I installed it. I've not downloaded any viruses or anything like that. Can…
