有没有办法获取整数，wc返回的bash？
原文链接：https://www.f2er.com/bash/392155.html基本上我想把行号和字计数写入文件名后的屏幕。
output：filename linecount wordcount
这里是我到目前为止：
files=`ls`
for f in $files;
do
if [ ! -d $f ] #only print out information about files !directories
then
# some way of getting the wc integers into shell variables and then printing them
echo "$f $lines $ words"
fi
done
