cronの多重起動防止

基本方針

pidof コマンドを使う (稼働中のプロセスIDを返す)

• || で繋げてコマンド実行すればOK
• /proc/$$/comm あたりと同じ動作なので、スクリプトの場合 bash が入ってしまう
• pidof -x foo のように -x を入れるとスクリプトは対応できる

誤検出

/* npm install acorn acorn-walk */
/* usage: nodejs print-func.js foo.js --call */

let mode  = 'name';
let index = process.argv.findIndex(function(e) { return e == "--call"});
if (index > 0) { process.argv.splice(index, 1); mode = 'call'; }

let filename = process.argv[2];
if (!filename) throw "file not found";
