So I was looking for a way to easily take android screenshots in a lossless image format, since my OEM only does jpeg.
Didn't want to install another adware and wound up with the adb shell screencap command since I need the pictures on my PC anyways.
But instead of a nice one-liner like
adb shell screencap -p > screenshot.png
I need 3 lines in a bash script.
Can we please just end the line ending wars?

I know it sucks ass.
Also fuck the whole CL or RF or CLRF shit.

Any difference via cygwin or wsl?

@SortOfTested those might be worth a shot, or hell even the mingw bash that is installed with Git on windows.

@SortOfTested

Don't have cygwin, I have a linux VM (not wsl because wsl broke, I set up the VM and now that wsl2 is out I'm too lazy to migrate back) but USB debugging requires adb to run on the host so... (If only Hyper-V had USB passthrough like VirtualBox)

Tried git bash, no luck there, and I'm pretty sure the fault lies within adb itself anyways. I tried

ssh me@windows "adb shell screencap -p" > screenshot.png

from linux and the png still comes out invalid.

Maybe debugging over the network and running adb in linux could work? No Idea how to set that up tho

Update: Network debugging is as easy as pie. I can now wirelessly remote control my unrooted phone with github.com/oberien/adb-remote-control from linux (Nevermind the 1fps and no downsampling). And adb screencap -p | display png:- works too!
