awk中的多行注释

#!/usr/bin/awk -f
0 {
    You can use
     0 to cause
     a block to
     not execute
     or be parsed
}

{
    print $2,$1,$3
    if (0) {
        You can use if (0)
        in a similar mAnner
        inside a block
    }
    sum += $4
}

0 && /pattern/ {    # prepend "0 &&" to other conditions to turn off a block
    print
}

很高兴能够在调试期间使用多行注释来注释掉代码段.我不一定会将此技术用于文档,因为可能无法保证不会因语法错误而解析非代码文本.

它似乎也在mawk中工作.
