在bash中仅从wc获得整数
有没有办法得到wc在bash中返回的整数? 基本上,我想在文件名之后将行号和字数写入屏幕。 output: filename linecount wordcount 这是我到目前为止的内容: 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
