<9>.vi、vim、 nano

我更喜欢nano

1. ctrl+W 搜索
2. ctrl+X 退出

<10>. 搜索、替换、模式匹配 文本gerp、sed、awk

1. 搜索文本gerp

┌──(root💀kali)-[/home/kali/mydirectory]
└─# grep Hello  myfile3            
Hello World222
Hello World333
                                                                            
┌──(root💀kali)-[/home/kali/mydirectory]
└─# grep 222 myfile3   
Hello World222

2. 替换文本sed

┌──(root💀kali)-[/home/kali/mydirectory]
└─# cat myfile3         
Hello World222
Hello World333
                                                                            
┌──(root💀kali)-[/home/kali/mydirectory]
└─# sed 's/2/0/' myfile3
Hello World022
Hello World333

3. 模式匹配 awk

┌──(root💀kali)-[/home/kali/mydirectory]
└─# cat myfile3         
1. Hello World222
2. Hello World333
3. 3
4. 4
5. 555
                                                                            
┌──(root💀kali)-[/home/kali/mydirectory]
└─# awk '$1<2' myfile3       
1. Hello World222
                                                                            
┌──(root💀kali)-[/home/kali/mydirectory]
└─# awk '$1<3' myfile3
1. Hello World222
2. Hello World333
