we have running tomcat server and in server.xml file we have password=secret I want to search and replace my password with xxxxxxx string. how do i craft regex for it? following is line where password i located in server.xml file
<Resource auth="Container" description="Database connection for Production" driverClassName="oracle.jdbc.OracleDriver" factory="org.apache.commons.dbcp.BasicDataSourceFactory" maxActive="25" maxIdle="5" maxWait="5000" name="jdbc/osdb" password="secret" type="javax.sql.DataSource" url="jdbc:oracle:thin:#DB0001" username="admin"/>
Would something like:
sed -i 's/password="[a-zA-Z0-9]\+"/password="foo"/g' server.xml
do the job for you or are you expecting there to be other lines like password="xyz" ?

I have a complex problem. Below is the ndxconfig.ini file I want to Edit
# /etc/ndxconfig.ini will override this file
# if APP_ID is added in service propery, service discovery will be using marathon;
# HOST/PORT specified will override values retrieved from marathon
[MARATHON]
HOSTS = {{ ','.join(groups['marathon'])}}
PORT = 8080
PROTOCOL = http
SECRET = SGpQIcjK2P7RYnrdimhhhGg7i8MdmUqwvA2JlzbyujFS4mR8M88svI7RfNWt5rnKy4WHnAihEZmmIUb940bnlYmnu47HdUHE
[MYSQL]
; APP_ID = /neon/infra/mysql
HOST = {{keepalived_mysql_virtual_ip}}
PORT = 3306
SECRET = tIUFN1rjjDBdEXUsOJjPEtdieg8KhwTzierD48JsgDeYc84DD6Uy5a6kzHfKolq1MNS1DKwlSqxENk33UulJd9DPHPzYCxFm
I want to change specifically marathon protocol conf from http to https. Not other's protocol conf. I have to match PROTOCOL = http 3 lines below the [MARATHON] line. I researched and couldn't find any solution. There's only 1 line below sed solutions.
One idea stuck mine was somehow specially grep [MARATHON] and 3 lines below and tail 1 line. I don't know.
How can fix this? Please Help.
Solution found here
sed '/\[MARATHON\]/{N;N;N;s/http/https/;}' <file>
If you have python available, you can use crudini:
crudini --set ndxconfig.ini MARATHON protocol https
This screams for ed, which treats the file as a whole, not processing it a line at a time like sed (And also doesn't depend on the availability of the non-posix -i extension to sed for in-place editing of files):
ed -s ndxconfig.ini <<'EOF'
/MARATHON/;/^$/ s/^PROTOCOL = http$/PROTOCOL = https/
w
EOF
This will replace the PROTOCOL line in the block that starts with a line matching MARATHON and ending with a blank line. The protocol entry can be the second, third, fourth, etc. line; doesn't matter. If the protocol is already https, it won't do anything (Except print a question mark)
Below lines in my jenkins job configuration Execute shell retrieves jira key
JIRA_KEY=$(curl --request GET "http://jenkins-server/job/myProject/job/mySubProject/job/myComponent/${BUILD_NUMBER}/api/xml?xpath=/*/changeSet/item/comment" | sed -e "s/<comment>\(.*\)<\/comment>/\1/")
JIRA_KEY=$(echo $JIRA_KEY | cut -c10-17)
But in case if text doesn't start with jira key then as per the current logic it will assign any text in the range of 10-17. I need to store empty string "" in the variable JIRA_KEY when jira key is not present in the <comment>, how can we do that?

As I mentioned in comment section it is not clear which output you need, so based on some assumptions, could you please try following and let me know on same.
I- If you need all the strings between to then you could run following.
awk '/<\/comment>/{a="";next}/<comment>/{a=1;next}a' Input_file
II- If you need to find only JRA string between to then you could do following.
awk '/<\/comment>/{a="";next}/<comment>/{a=1;next} a && /JRA/{match($0,/[a-zA-Z]+[^ ]*/);print substr($0,RSTART,RLENGTH)}' Input_file
I want to add the info below into the file usr/local/nagios/etc/hosts.cfg but want to do it just below ##company in the hosts.cfg file. My setup script will contain the info that needs to be added
I have spend hours trying to get sed to just add a line into a file after a marker but to no avail
define host{
use linux-box
host_name $host_name
alias $alias
address $ip
parents $parent
notification_period 24x7
notification_interval 5
}
Previously I used
cat <> /path /filename
EOT
but now I need to do it in specif places in the file
Given the following file:
# some content
###company
If I run the following command:
sed -i 's/###company/&\ndefine host {\nuse host\nhost_name HOSTNAME/' file
Now, the contents of file are:
# some content
###company
define host {
use host
host_name HOSTNAME
Is this what you're looking for?
I'm trying to math strings in /var/log/secure with regex to get if there is a ssh authentication failure.
If there is an authentication failure it will look like this in the log file:
Oct 31 07:52:41 logserver sshd[17041]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=localhost
I tried do something like this:
"\\<sshd[^:]*: pam_unix(sshd:auth): authentication failure; ./* \\>"
But it dosen't not work. I'd appreciate if some could help me with regular expressions.
This is on a CentOS 7 machine and the regex is for collectd's plugin tail.
In the collectd .conf you could likely use one of the following:
<Plugin "tail">
<File "/var/log/secure">
...
<Match>
Option 1:
Regex "authentication failure"
Option 2:
Regex "sshd:auth[^:]*: authentication failure;"
Option 3:
Regex "authentication failure|authentication|failure"
Where option 1 and 2 should be the most precise for matching, and option 3 more generalized. Option 1 finds the exact phrase authentication failure, Option 2 finds the exact phrase along with (sshd:auth): preceding it, and Option 3 finds the exact phrase or "authentication" or "failure".
</Match>
</File>
</Plugin>
What would the easiest way to parse the Data section from this STAF command be?
Cannot find a STAF parameter which I can pass to the command to automatically do this,
so looks like parsing/regular expression might be best option?
Note: I do not want to use any external libraries.
[root#source ~]# STAF target PROCESS START SHELL COMMAND "ls" WAIT RETURNSTDOUT
Response
--------
{
Return Code: 0
Key : <None>
Files : [
{
Return Code: 0
Data : myFile.txt
myFile2.txt
myFile3.txt
}
]
}
Instead I would like the output/result to be formated like ..
[root#source ~]# STAF target PROCESS START SHELL COMMAND "ls" WAIT RETURNSTDOUT
myFile.txt
myFile2.txt
myFile3.txt
Best way to this is Create a XML file and use python script to access the data part of STAFResult since STAF Return data in Marshalled form as "CONTENT" and python can be use to grab that.
I will try to explain it with simple example, Its an HTTP request to server.
<stafcmd>
<location>'%s'%machineName</location>
<service>'http'</service>
<request>'DOGET URL %s?phno=%s&shortCode=%s&query=%s' % (url, phno, shortCode, escapeQuery)</request>
</stafcmd>
<if expr="RC == 0">
<sequence>
<call function="'func_Script'"></call>
<if expr="rc == 0"> <!-- Pass At First Query -->
<sequence>
<message>'PASS#Fisrt HTTPRequest: Keyword = %s,\nRequired Response = %s,\ncontent=%s' %(query, response, content)</message>
<tcstatus result="'pass'">'Pass:' </tcstatus>
</sequence>
<else> <!-- Check For MORE -->
<call function="'Validate_QueryMore'"> </call>
</else>
</if>
</sequence>
<else>
<message>'ERROR: HTTPRequest QUERY : RC = %s Result= %s' %(rc,STAFResult)</message>
</else>
</if>
<function name="func_Script">
<script>
import re
content = STAFResult['content'].lower()
response = response.lower()
test = content.find(response)
if test != -1:
rc = 0
else:
rc = 1
</script>
</function>
Hope It will give you some Help.
You can pipe the output of your command through an sed script that will filter out only the filenames for you. Here's a first cut:
sed -ne '/^[a-z]/p;/Data/s/[^:]*: \(.*\)/\1/p'
The idea is: If a line starts with a lower-case letter, that's a file name (expression up to the first semicolon). If the string "Data" is on the line, take everything that comes after the first colon in that line (expression after the semicolon). Everything else is ignored.
You might want to be more specific than just expecting a lower-case letter at the beginning (this would filter out the "Response" line at the beginning, but if your filename might start with an upper-case letter, that won't work). Also, just looking for the string "Data" might be a bit too general -- that string might occur in the filename as well. But hopefully you get the idea. To use this, run your command like this:
STAF ... | sed -ne ...
