shell命令批量处理文件

1、请问如何从一个关键字文本集合里用grep批量筛选另一个文本？

grep -f seed.txt file.txtgrep -vf seed.txt file.txt

可扩展：

#!/bin/bashfor file in  ~/zjx/order_succ/*do    #filename=$(basename $file)    cat $file | while read line    do    echo ${line}|awk -F ',' '{print $2}' >> oo.txtdonedoneecho 'finish oo.txt!'cd ~/zjx/for file2 in ~/zjx/log/*do    #filename=$(basename $file2)    grep -vf oo.txt $file2 >> other_result.txtdoneecho 'finish other_result.txt!'
