In an AHK script, I'm trying to redirect the binary output from adb to a file. adb exec-out screencap -p > Screenshot.png However, it looks like AHK's RunWait doesn't really handle binary output.

How can I make this work?

I've toyed around with StdoutToVar and CMDRet, but don't really know what I'm doing.

• 1 Redirecting stdout via greater sign in a command is handled by the command interpreter like cmd.ese. Thus you may want to execute the ad command in cmd.exe instead of AHK itself, then redirection will also work. cmd.exe /c adb exec-out ... > Screenshot.png You may need to do some experiments to find the correct quoting for the redirect to screenshot.png part to be executed on PC side in cmd. – Robert Commented Mar 23 at 0:04
• @Robert That's what I've been doing. runWait, %ComSpec% /c adb exec-out screencap -p > Screenshot.png. When I run the same command directly in the windows terminal, it works fine. When I run it via runWait, the file is corrupt. – hoytdj Commented Mar 23 at 2:05
• Never mind, you're right. It was just a quoting issue. After playing around for way to long with Gdip functions, I ended up just needing an extra set of quotes around %command% – hoytdj Commented Mar 23 at 2:15

As Robert suggest it was just a matter of properly quoting. Here's what ended up working.

command := """" . adbPath . """ -s " . deviceAddress . " exec-out screencap -p > """ .  outputFile . """"
RunWait, %ComSpec% /c "%command%", , Hide
