Linux 之 nano 编辑器的使用

1.Bash脚本

1. 编写Bash脚本

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# nano pingscript.sh

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# cat pingscript.sh 
#!/bin/bash
echo "Usage: ./pingscript.sh [network]"
echo "example: ./pingscript.sh 192.168.159"

2. 赋予执行(x)权限

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# chmod 740 pingscript.sh 
                                                                                                                                                             
┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ls -l pingscript.sh    
-rwxr----- 1 root root 96 Mar 25 00:22 pingscript.sh

3. 查看环境变量,运行程序

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# echo $PATH                      
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games
                                                                                                                                                             
┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ./pingscript.sh 
Usage: ./pingscript.sh [network]
example: ./pingscript.sh 192.168.159

2. python脚本

1. Kali Linux默认已经安装了Python运行环境，运行下面的命令，可以查看当前Python版本。

┌──(kali㉿kali)-[~]
└─$ python --version
Python 2.7.18

2. 编写python脚本

#!/usr/bin/python
import socket

ip = raw_input("Enter the ip:")
port = input("Enter the port:")
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
if s.connect_ex((ip, port)):
    print "Port",port,"is closed"
else:
    print "Port", port, "is open"

3. 直接运行会提示没有权限

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ./pythonScript.py   
zsh: permission denied: ./pythonScript.py

4. 提权

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# chmod 740 pythonScript.py 
                                                                                                                                                 
┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ls -l pythonScript.py 
-rwxr----- 1 root root 255 Mar 25 03:56 pythonScript.py

5. 运行

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ./pythonScript.py
Enter the ip:192.168.159.129
Enter the port:8080
Port 8080 is closed

6. 打开8080端口再运行

┌──(root💀kali)-[/home/kali]
└─# nc -lvp 8080                        
listening on [any] 8080 ...
192.168.159.129: inverse host lookup failed: Unknown host
connect to [192.168.159.129] from (UNKNOWN) [192.168.159.129] 52338

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ./pythonScript.py
Enter the ip:192.168.159.129
Enter the port:8080
Port 8080 is open

7. 安装了Python3

┌──(root💀kali)-[/home/kali]
└─# wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

8. 解压安装python3

root@kali:tar -zxvf Python-3.7.0.tgz

root@kali:mkdir /usr/local/Python-3.7

root@kali:cd Python-3.7.0/ #进入到解压缩的那个目录，不是新创建的目录

root@kali:Python-3.7.0# ./configure --enable-optimizations --prefix=/usr/local/python3.7/

root@kali:Python-3.7.0# make && make install

4. 安装pip3

root@kali:~# apt-get update

root@kali:~# apt-get install python-pip3

等待安装即可。

.pythonScript.py

3.C脚本

1. 编写C脚本

# Hello.c
#include<stdio.h>
int main(int argc,char *argv[]){
    if(argc < 2){
        printf("Pass your name as an argument\n"); 
    }else{
        printf("Hello %s\n", argv[1]);
    }
    return 0;
}

2. 编译

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# gcc Hello.c -o Hello.out

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ls
Hello.c  Hello.out  pingscript.sh  pythonScript.py

3. 运行

┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ./Hello.out
Pass your name as an argument
                                                                                                                                                 
┌──(root💀kali)-[/home/kali/mydirectory/BashScript]
└─# ./Hello.out xiaoming
Hello xiaoming
