awk display the match and 2 lines after the match is found.
Hello, can someone help me how to find a word and 2 lines after it and then send the output to another file.
For example, here is myfile1.txt. I want to search for "Error" and 2 lines below it and send it to myfile2.txt
I tried with grep -A but it's not supported on my system.
I tried with awk, but I am not getting the first line displayed.
Here is myfile1.txt
**My Program Erorr ddmmyy hh:mm:ss My Program Error
**Port 123 terminated
**ID PIN 12345
Comamnd Successful
Command Terminated
Command Successful
Command Terminated
**My Program Erorr ddmmyy hh:mm:ss My Program Error
**Port 345 terminated
**ID PIN 67890
Comamnd Successful
Command Terminated
Command Successful
Command Terminated
**My Program Erorr ddmmyy hh:mm:ss My Program Error
**Port 678 terminated
**ID PIN 13579
Comamnd Successful
Command Terminated
Command Successful
Command Terminated
After I ran awk 'c-->3;/Error/{c=5}' myfile1.txt > myfile2.txt i get this
**Port 123 terminated
**ID PIN 12345
**Port 345 terminated
**ID PIN 67890
**Port 678 terminated
**ID PIN 13579
I want these lines to be displayed, but I want the line with the error in it, too.
so myfile2.txt should look like this:
**My Program Erorr ddmmyy hh:mm:ss My Program Error
**Port 123 terminated
**ID PIN 12345
**My Program Erorr ddmmyy hh:mm:ss My Program Error
**Port 345 terminated
**ID PIN 67890
**My Program Erorr ddmmyy hh:mm:ss My Program Error
**Port 678 terminated
**ID PIN 13579
What am I doing wrong?
Thank you
