我在行和列上有许多格式完全相同的csv文件。在下面的示例中，我仅提供3个文件作为输入，但是我有很多具有相同特征的文件
目的是对每个输入文件执行以下操作：
在第3、11和12行中取值。
第一个文件中的示例
6174
15
3
然后，从第17到25行打印第一列。
对所有输入文件执行相同的过程，并输出包含所有已读取文件的所有信息的文件。
示例（输出1）
6174,6176,6178
15,17,14
3,3,4
1.6,1.6,1.6
1.6,1.6,1.6
1.6,1.6,1.6
1.7,1.7,1.7
1.8,1.8,1.8
1.9,1.9,1.9
2.1,2.1,2.1
2.3,2.3,2.3
为所有文件和第一列完成该过程时。其余的列都做同样的事情
最后，创建的总文件输出将为10个文件，因为每个文件中有10列。
输入文件（例如3个）

这是我用来获取第一个输出的代码。选择第一列。我应该对其余9列做同样的事情。
ls *.csv > filelist.txt
for f in `cat filelist.txt`; do
p1=`awk -F, 'NR==3{print $1}' $f | awk '{print $NF}'`
p2=`awk -F, 'NR==11{print $1}' $f | awk '{print $NF}'`
p3=`awk -F, 'NR==12{print $1}' $f | awk '{print $(NF-1)}'`
echo $p1 > a-$f
echo $p2 >> a-$f
echo $p3 >> a-$f
sed -n '17,25p' $f | awk -F, '{print $1}' >> a-$f
paste *a-* | awk -v OFS=',' '{$1=$1}1' > file1
done
rm -f *a-*
谢谢。
