linux脚本读取文件内容

如题是本文介绍的内容

一般而言有三种流行的写法：

如下：

写法一：

#!/bin/bash

while read line

do

echo $line

done < file(待读取的文件)

写法二：

#!/bin/bash

cat file(待读取的文件) | while read line

do

echo $line

done

写法三：

for line in `cat file(待读取的文件)`

do

echo $line

done

个人比较推荐的一种写法是：

1 2 3 4 5 6 7 8

#!/bin/bash IFS=':' echo "Employee Names:" echo "---------------" while read name empid dept do     echo "$name is part of $dept department" done < employees.txt

需要读入的文件名字 叫 employees.txt 这个位置也可以写绝对路径

文件内容：

Emma Thomas:100:Marketing

Alex Jason:200:Sales

Madison Randy:300:Product Development

Sanjay Gupta:400:Support

Nisha Singh:500:Sales

输出效果：

Employee Names:
