node.js - 请问这句sh怎么理解 exec "`dirname "$0"`/node" "$0" "$@"

Question

exec "dirname "$0"/node" "$0" "$@"
从nodejs里看到的不懂

Answer 1

rrreee                    # 这个脚本自己的路径
"`dirname "rrreee"`"/node # 这个脚本同个目录下的node程序的路径
$@                    # 这个脚本这次被执行时的命令行参数

Together it is... Use the node program in the same directory to explain the script itself
