只打印列匹配列 -n

只打印匹配列的内容

 

public@share:~/zhaoyh$ sed -n '/Linux/p' input 1. Linux Sysadmin, Linux Scripting etc.4. Storage in Linux

 只打印匹配列的行号

 

public@share:~/zhaoyh$ sed -n '/Linux/=' input 25

如果没有-n 会怎么样? 

public@share:~/zhaoyh$ sed  '/Linux/p' input # Instruction Guides1. Linux Sysadmin, Linux Scripting etc.1. Linux Sysadmin, Linux Scripting etc.2. Databases - Oracle, mySQL etc.3. Security (Firewall, Network, Online Security etc)4. Storage in Linux4. Storage in Linux5. Productivity (Too many technologies to explore, not much time available)#  Additional FAQS6.
