[linux] crontab 命令裡面 % 的意思是斷行

今天設計了新的java參數讓cronjob跑，
發現cronjob沒有再跑，

後來上網查了發現 是 % 這個符號的關係，
這符號的意思是換行，所以這符號後面的參數我的jar檔就吃不到啦~

引用

A <percent-sign> character in this field shall be translated 
to a <newline<. Any character preceded by a <backslash> (including the '%' ) 
shall cause that character to be treated literally. Only the first 
line (up to a '%' or end-of-line) of the command field shall be 
executed by the command interpreter. The other lines shall 
be made available to the command as standard input.
