从bash文件中读取星号字符(*) [英] Reading asterisk character (*) from a file in bash

问题描述

我正在从.txt文件中提取行:说出Input.txt

I am taking lines from a .txt file: Say Input.txt

a
*
b

然后我正在阅读:

#!/bin/bash
file=$1

ans=0
while  read -r line || [[ -n "$line" ]]
do
echo $line
done < $file # passing the file

我将得到以下输出

a
test main.py sic.sh
b

显示我目录的文件而不是*

Where files of my directory are being shown instead of *

我想根据需要检测/读取*的* char做出一些决定?

I want to take some decisions on the basis of * char for which I need to detect/read * ?

推荐答案

始终引用变量:

#!/bin/bash
file="$1"

ans=0
while  read -r line || [[ -n "$line" ]]
do
    echo "$line"
done < "$file" # passing the file
