Here's a little puzzle for you. Can you figure out the purpose of this one-off shell script I just wrote?
If you post an answer put it behind a CW so you don't spoil it for others!

I really despise Linux shell script from time to time. Why does the first process to get the standard input consume it? WHY?!
I wish I could tag this as a cognito hazard...

シェルスクリプトで引数を（スペース等で）壊さずに引き継ぐときの正解は"$@"で、
sh -cを使う場合はsh -c '..."$@"...' -- "$@"という話、
忘れそうなので以下にまとめました。

I spent WAY too long on a simple “don’t run bash script if it’s already running” solution. Here’s what I eventually worked out in case it’s helpful #bash #shellscript
OTHER_PIDS=$( pidof -x -o %PPID "$( basename $0 )" )
if [ -n "${OTHER_PIDS}" ]; then
# script is already running
exit
fi
