Delete from another file that matched on log file

UNIX for Beginners Q & A

I want to write a script using Oscam Cardsharing server
this is my test:

cat oscam.log | grep "error"

sample output:

2018/10/17 16:43:07 5C94A12E p    (cccam) cccam(r) test.dyndns.org: login failed, error

Once I've found an error, I need to remove its information inside another file :
oscam.server

[reader] label                         = test.dyndns.org 
protocol                      = cccam 
device                        = test.dyndns.org,12000 
key                           = 0102030405060708091011121314 
user                          = 12345 
password                      = 12345 
inactivitytimeout             = 30 
group                         = 1 
cccversion                    = 2.1.2 
cccmaxhops                    = 0 
cccmindown                    = 1 
ccckeepalive                  = 1  

blalbal 
blalblalb 
blalblalb 
lablalb

I need to delete those " test.dyndns.org " lines that matched. I would like to keep only the following :

blalbal 
blalblalb 
blalblalb 
lablalb

So far, I've tried the following code :

awk '/test.dyndns.org/{while(getline && $1 != ""){}}1' oscam.server

#output is :

[reader]  

blalbal 
blalblalb 
blalblalb 
lablalb

But the line [reader] is still present. What could I do to remove the block entirely?

i dont know how variable in perl because will be random url that contains words or only numbers i didnt prefer this method i gave an example

perl -sp0e 's/\[reader\]((?!\n\n).)*\Q$input\E((?!\n\n).)*((\n\n)|(\n?\Z))//sig' -- -input="<DESIRED INPUT HERE>" oscam.server

Welcome to the forum.

The structure of your "oscam.server" is not quite clear; it wasn't before I inserted the required CODE tags for data. It's all in one line; please edit your post and correct the sample data.

Is the [reader] line immediately adjacent to the pattern line? Or do we just have to match itself?

Check again, now formatted, im sorry im totally new in this forum

No problem. Your code snippet applied to the file as is now yields

awk '/test.dyndns.org/{while(getline && $1 != ""){}}1' file

blalbal 
blalblalb 
blalblalb 
lablalb

which is close to what you want, no [reader] line.
Does that file end after the "blabla...", or do we need a termination criterion?

Yep, till delete the first blank line, but also delete

[reader]

, that matching from the log, but how to input beetween 2 words this search? I didn't found yet

Please rephrase.
