Many screenshots within a limited time saved directly, without asking for a filename
Shutter has an option to automatically save screenshots, incrementing the filename each time.
Edit ➜ Preferences ➜ Main ➜ Save :
To make Shutter take the screenshots when you hit PrtScr,
go to Edit ➜ Preferences ➜ Keyboard and check the Capture checkbox:
If you don't want the Shutter window to pop up every time you take a screenshot, go to Edit ➜ Preferences ➜ Behavior and uncheck Present main window after taking a screenshot :
Shutter is quite impressive, with lots of features, but still requires user interaction to capture the window that currently has the focus. I.e., when Edit->Preferences->Keyboard->Capture with selection is enabled, and "Window" is specified, Shutter still waits for the user to select the desired window, instead of automatically capturing the window that currently has the focus.
For fully automatic screen captures I found that scrot
works perfectly, both for full screen captures, and capturing the current window (via the -u
option), as described here:
http://www.khattam.info/save-screenshots-in-ubuntu-automatically-when-printscreen-key-is-pressed-2009-05-12.html The only (very minor) issue I saw with scrot is that it cannot take more than one screen shot per second. But since it seems to take longer than a second to complete a screen capture anyway, this doesn't seem like much of an issue.
I enabled scrot (after installing it via Synaptic Package Manager) by changing my <Print>
and <Alt><Print>
hotkey bindings to do full screen and current window captures (respectively) and it works perfectly, as described here: How can I restore default keyboard shortcuts?
In gconf-editor I set them to save to the /tmp directory by specifying these associations under apps->metacity->global_keybindings:
run_command_screenshot
->Print
run_command_window_screenshot
-><Alt>Print
and these associations under apps->metacity->keybinding_commands:
command_screenshot
->/usr/bin/scrot '/tmp/Screenshot-%Y-%m-%d-%H%M%S.png'
command_window_screenshot
->/usr/bin/scrot -u '/tmp/Screenshot-%Y-%m-%d-%H%M%S.png'
I did not have to restart anything for these changes to take effect.
I am running Ubuntu 10.04, Gnome Desktop 2.30.2.
As for scrot - in order to take screenshots more frequent then one per second I suggest using the following command bound with Key Shortcut:
scrot ~/shots/'%Y-%m-%d_%H-%M-%S.png' -e 'TMPSCRN=$f; mv $f $${TMPSCRN%.png}-`date +%3N`.png'
since scrot doesn't support %N
as nanoseconds it is quite good workarround.
Note that, here in example nanoseconds were shrinked into miliseconds using first 3 digits from nanoseconds pattern expression: %3N
. Local variable $TMPSCRN
was used because string manipulation on shrot $f
filename variable I found myself hard to implement yet impossible.
If you'd like to take the shots in .jpg
format, you need to replace all occurances of .png
with .jpg
