如何为“commandx”添加循环

tst.awk

BEGIN { FS="," }
{
    printf "echo %s %s", $1, $2
    for (i=3; i<=NF;i=i+1) {
        printf " commandx %s", $i
        }
    print "command"
}

输出：

echo "a1" "b1" commandx "c1" command
echo "a2" "b2" commandx "c2" commandx "d2" command
echo "a3" "b3" commandx "c3" commandx "d3" commandx "e3" command

echo "a1" "b1" command1 "c1" command
echo "a2" "b2" command1 "c2" command2 "d2" command
echo "a3" "b3" command1 "c3" command2 "d3" command3 "e3" command

预期输出：

echo "a1" "b1" commandx "c1" command
echo "a2" "b2" commandx "c2" commandx "d2" command
echo "a3" "b3" commandx "c3" commandx "d3" commandx "e3" command

echo "a1" "b1" command1 "c1" command
echo "a2" "b2" command1 "c2" command2 "d2" command
echo "a3" "b3" command1 "c3" command2 "d3" command3 "e3" command

使用

BEGIN { FS="," }
{
    output = sprintf("echo %s %s", $1, $2)
    for (i=3; i<=NF;i=i+1) {
        output = output sprintf(" command%n %s",i-2, $i)
        }
    output = output "command"
    print output
}

BEGIN{FS=“，”}
{
输出=sprintf（“回显%s%s”，$1，$2）
对于（i=3；i假设commandx
中的x
被假定为以不断增加的数字填充（从1
开始，直到NF-2
）：
试着改变
printf“commandx%s”，$i
到
printf（“命令%d%s”，i-2，i）
?
echo "a1" "b1" command1 "c1" command
echo "a2" "b2" command1 "c2" command2 "d2" command
echo "a3" "b3" command1 "c3" command2 "d3" command3 "e3" command
