I have errors in the log that span multiple lines and I can find say the 2nd line in the log of this error using an unique word. However, this only gets me the line that the word appears in not the full error which may be 3 or four line long. So if there way to display say the line before a match and after a match. Any idea guys?
Thanks in advance.
be precise by giving an example
for example here is some text of log file

keep on going.......................
So what i want is to grep and ERROR, but if i grep error <file name> then it will display only one line of error.
i want to place a logic so that starting from line ERROR until INFO i was all the lines.. like

I hope i am clear now.
If you are sure that the error lines will always have an INFO at the end, you may use:
awk '/ERROR/,/INFO/{ if( $0 !~ /INFO/ )print }' infile
Thanks lot its really nice awk....
But you are right i have WARNING also in between in the file.
I tried with the command like this
awk '/ERROR/,/INFO/||/WARNING/{ if( $0 !~ /INFO/ || /WARNING/ )print }' infile
But getting warning line also in output, any idea, am i missing anything?
