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

Try sed:

sed -n '/My Program Error/{N;N;p}' myfile1.txt

Please use code tags when posting i/output or code.
Your awk command is almost correct, you were really close, just add print:

awk 'c-->3;/Error/{c=5; print}'

awk '/Error/{print; getline; print; getline; print}'

awk '/Error/{getline a; getline b; print $0,a,b }' OFS="\n" err.log

Cool! Tried it and this one works as what he wanted.
Would you mind explaining the command a little?
I can only assume N is new line.

The codes 1 and 2 are what I was looking for. Is there a way to add a blank line after the third line.

Never mind, I was able to figure it out.
awk '/Error/{print; getline; print; getline; print; print ""}' did the trick insertinbg ablank line.
