shell スクリプト二重起動防止

More than 3 years have passed since last update.

特に説明する部分でもないですが、cron等の繰り返し設定で2重に起動しないようにするbashです。該当シェルスクリプトの先頭に追加しておくと便利

# 二重起動防止
_process=`basename $0`

_pcnt=`pgrep -fo ${_process} | wc -l`

if [ ${_pcnt} -gt 1 ]; then
  echo "This script has been running now. proc : ${_pcnt}"
  exit 1
fi
