我正在尝试搜索存储在awk数组中的模式“a”从file1读取然后在file2的4rth列中搜索，以下命令工作正常
awk -F" " 'NR==FNR{a[NR]=$1;next}{for (i in a){ if($4 ~ a[i])print $0}}' file1 file2
但是如果我在if更改命令以搜索file2的4rth列的开头，如下所示，它不起作用，有什么建议吗？
awk -F" " 'NR==FNR{a[NR]=$1;next}{for (i in a){ if($4 ~ "^a[i]" )print $0}}' file1 file2
可以修改第二个命令来搜索file2中4rth列开头的数组元素吗？
