func.sh

一个awk和bsh混合编程的例子

echo "aaa"|awk '{
			x=1
			if (x==1) {
				printf "bbbb\n";
			}
			foo(4);
			num=extractAttrs("$FDN:userlabel:", attrs, ":");
			printf "----------------------\n";
			
			for (x=1;x<=num;x+=1)
			{
				printf "%s -- %s\n", x,attrs[x];
			}
	}
	function foo(b) { a = sqrt(b) ; print a }
	function extractAttrs(in_string,array,seperator) {
		ix=1;
		attrs_string_tmp=in_string;
		pos_sep_req=index(attrs_string_tmp,seperator);
		while (pos_sep_req != 0 && length(attrs_string_tmp) !=0)
		{
			attr_str=substr(attrs_string_tmp,1,pos_sep_req-1);
			array[ix]=attr_str;
			ix+=1;
			attrs_string_tmp=substr(attrs_string_tmp,pos_sep_req+1);
			pos_sep_req=index(attrs_string_tmp,seperator);
		}
		if (length(attrs_string_tmp) !=0)
		{
			attr_str=substr(attrs_string_tmp,1);
			array[ix]=attr_str;
		}
		else
		{
			ix-=1;
		}
		return ix;
