If interested, I've recently made a similar script that works a little differently. I'll put it here as having options and choice is a good thing. mv "$(xfce4-screenshooter -fo ls)" ~/Screenshots ( sleep 3 ) qvm-move-to-vm Base ~/Screenshots/screenshot_* I know many here don't need an explanation since it's a rather straight forward simple working script that "just works", but for those who may need it, here are some considerations to take into account about the script: - The mv "$() part of the script serves as a function to remove "save as" and instead auto-save with the name screenshot_+date+timestamp. - Never remove the -o attribute if you want the mv "$() part of the script working. - The first line decides where to save the screenshot, and the third line pulls the screenshot from this location. By narrowing down an empty folder specifically this use-case, you avoid false positive transfers, although those are unlikely in dom0 anyway. - By default this scripts sends screenshots to an offline AppVM that I frequently have running in the background for offline applications and daily used data. - AppVM name used: Base - Fullscreen, keep the f attribute. - Region, change -fo to -ro - Window, change -fo to -wo - The screenshot_* part, will move any files or folders beginning with screenshot_*, at the given address location. If you got older screenshots there, then they will also be moved. This should not be a big problem though, if you only use these scripts and keep the folder empty. - You can also optionally keybind scripts to different AppVM's, so you don't have to move them a second time from the standard AppVM. - Need longer time, for example to carefully select text in region screenshots, then expand the sleep timer to, say, 20 seconds. - Make scripts executable and put them in dom0 $HOME/ folder. Then simply just keybind them in Qubes Menu --> System-Tools --> Keyboard ---> Shortcut tab. - If dom0 is ever compromised, or the AppVM you backup your scripts to is compromised, be sure to check the scripts before putting them back in dom0 in the future. My own favourite version is region selection, set to 10 seconds, keybinded to the Screenshot key. mv "$(xfce4-screenshooter -ro ls)" ~/Screenshots ( sleep 10 ) qvm-move-to-vm Base ~/Screenshots/Screenshot_* All the others are scripted too, but I need to hold down Ctrl key, shift key, etc. to make those work. I also keybind for different AppVM's, where I include a letter, where the letter denotes the AppVM. For example shift+w+printscreen, will send a screenshot to my work AppVM, while shift+s+printscreen sends the screenshot to my Study AppVM. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
