shell read 文件

cat true line filename read line lena pro oot 內置

cat filename.txt |while read LINE
do
        echo $LINE
done
# LINE在這裏面只是隨便一個變量,並不是內置

或者

#!/bin/bash

while read aa
do
        echo $aa
done< filename.txt
#這種格式看起來更好
#!/bin/bash
myfile=filename.txt
count=0

cat $myfile |while read LINE
do
        echo $LINE
        let count=count+1
        echo $count line
done
