command linescreen capture
I would like to rename the "screencapture" utility triggered with the shift+cmd+3 keys, in order to take screenshots from a program that recognizes and disables this utility.
Specifically, I want a different name to appear under ps when that utility is running.
Is there a way to rename or alias this utility system-wide?
The -l option requires an argument for the ID of the window:
$ screencapture -l
screencapture: illegal option -- l
usage: screencapture [-icMPmwsWxSCUtoa] [files]
-c force screen capture to go to the clipboard
-C capture the cursor as well as the screen. only in non-interactive modes
-d display errors to the user graphically
-i capture screen interactively, by selection or window
control key - causes screen shot to go to clipboard
space key - toggle between mouse selection and
window selection modes
escape key - cancels interactive screen shot
-m only capture the main monitor, undefined if -i is set
-M screen capture output will go to a new Mail message
-o in window capture mode, do not capture the shadow of the window
-P screen capture output will open in Preview
-s only allow mouse selection mode
-S in window capture mode, capture the screen not the window
-t<format> image format to create, default is png (other options include pdf, jpg, tiff and other formats)
-T<seconds> Take the picture after a delay of <seconds>, default is 5
-w only allow window selection mode
-W start interaction in window selection mode
-x do not play sounds
-a do not include windows attached to selected windows
-r do not add dpi meta data to image
-l<windowid> capture this windowsid
-R<x,y,w,h> capture screen rect
files where to save the screen capture, 1 file per screen
$ screencapture -l $(osascript -e 'tell app "Safari" to id of window 1') test.png
$
Or if you have an older version of OS X, screencapture might not include the -l option. At least in 10.8 the -l option is only shown in the help message and not on the man page.
osascript -e 'tell app "Appname" to id of window 1' doesn't work with all applications, but see these questions for other ways to find the IDs of windows:
Here is the most convenient solution (Taken from http://www.quora.com/How-can-I-get-my-retina-Mac-to-not-take-screenshots-that-are-too-big and modified a bit)
Use OsX embedded Automator to downsize screenshots automatically after they taken.

I think it is not that easy, but it is possible.
When calling
I get
I enter sudo mode and cd to /usr/sbin
I rename the screencapure programm :
And after that, I create a symlink to the old one:
now when calling capturescreen, It is called capturescreen. But when doing CMD+Shift+3, I get the screencapture process.
But You could fix that with creating a Service in Automator and create a Shell-Script-Action, simply calling "capturescreen ~/Desktop/Output.png"
And after that in the System-Preferences, Assign a Shortcut to the Service.
But you could also simply call Terminal and enter "capturescreen ~/Desktop/Output.png"
Even further, you can modify the screencapture action in automator to get the timestamp back and use it as the main tool for schooting screenshots.
