Top Forums Shell Programming and Scripting How to remove answers and explanation parts from a text file with lots of questions.? Post 303041669 by MadeInGermany on Monday 2nd of December 2019 02:32:34 AM

The task seems easy: delete the section between "Answer:" and "NO."
Doable with sed by means of the N command and a loop. But sed has a portability issue regarding N on the last line.
So awk is the first choice here.
Code:
awk '/^Answer:/{del=1} /^NO\./{del=0; print ""} del==0' test.txt

del==0 is true if del is not initialized. A true without action defaults to {print}.

NAME
ipa-csreplica-manage - Manage an IPA CS replica SYNOPSIS
ipa-csreplica-manage [OPTION]... [connect|disconnect|del|list|re-initialize|force-sync] DESCRIPTION
Manages the CA replication agreements of an IPA server. connect [SERVER_A] <SERVER_B> - Adds a new replication agreement between SERVER_A/localhost and SERVER_B disconnect [SERVER_A] <SERVER_B> - Removes a replication agreement between SERVER_A/localhost and SERVER_B del <SERVER> - Removes all replication agreements and data about SERVER list [SERVER] - Lists all the servers or the list of agreements of SERVER re-initialize - Forces a full re-initialization of the IPA CA server retrieving data from the server specified with the --from option force-sync - Immediately flush any data to be replicated from a server specified with the --from option The connect and disconnect options are used to manage the replication topology. When a replica is created it is only connected with the master that created it. The connect option may be used to connect it to other existing replicas. The disconnect option cannot be used to remove the last link of a replica. To remove a replica from the topology use the del option. If a replica is deleted and then re-added within a short time-frame then the 389-ds instance on the master that created it should be restarted before re-installing the replica. The master will have the old service principals cached which will cause replication to fail. OPTIONS
-H HOST, --host=HOST The IPA server to manage. The default is the machine on which the command is run Not honoured by the re-initialize command. -p DM_PASSWORD, --password=DM_PASSWORD The Directory Manager password to use for authentication -v, --verbose Provide additional information -f, --force Ignore some types of errors --from=SERVER The server to pull the data from, used by the re-initialize and force-sync commands. EXAMPLES
List a server's replication agreements. # ipa-csreplica-manage list srv1.example.com srv2.example.com srv3.example.com Re-initialize a replica: # ipa-csreplica-manage re-initialize --from srv2.example.com This will re-initialize the data on the server where you execute the command, retrieving the data from the srv2.example.com replica Add a new replication agreement: # ipa-csreplica-manage connect srv2.example.com srv4.example.com Remove an existing replication agreement: # ipa-csreplica-manage disconnect srv1.example.com srv3.example.com Completely remove a replica: # ipa-csreplica-manage del srv4.example.com Using connect/disconnect you can manage the replication topology. EXIT STATUS
0 if the command was successful 1 if an error occurred IPA
