Splunk query not endswith - regex

I am just into learning of Splunk queries, I'm trying to grab a data from myfile.csv file based on the regex expression.
In particular, I'm looking forward, print only the rows where column fqdn not endswith udc.net and htc.com.
Below is my query which is working but i'm writing it twice.
| inputlookup myfile.csv
| regex support_group="^mygroup-Linux$"
| regex u_sec_dom="^Normal Secure$"
| regex fqdn!=".*?udc.net$"
| regex fqdn!=".*?htc.com$"
| where match(fqdn,".")
I am trying them to combine with | separeted but not working though...
| regex fqdn!="(.*?udc.net | ".*?htc.com)$"

You can do this with a search and where clause:
| inputlookup myfile.csv
| search support_group="mygroup-Linux" u_sec_dom="Normal Secure"
| where !match(fqdn,"udc.net$") AND !match(fqdn,"htc.com$")
Or just a single search clause:
| inputlookup myfile.csv
| search support_group="mygroup-Linux" u_sec_dom="Normal Secure" NOT (fqdn IN("*udc.net","*htc.com")
You can also rewrite the IN() thusly:
(fqdn="*udc.net" OR fqdn="*htc.com")

The combined regex will work if you omit the spaces on either side of the |. The extra spaces become part of the regex and prevent matches.
There's no need for the final where command. Splunk by default will display all events that match ..

Unable to format RegEx to handle Dollar Sign ($)

I am stuck trying to figure out how to get a RegEx text search to work with a dollar sign. Let's say I have two strings:
TestPerson One | 123456789 | ($100.00) | $0 | 03/27/2018 | Open
TestPerson Two | 987654321 | ($250.00) | ($25) | 03/27/2018 | Open
Using jQuery, I am creating the RegEx. If I was to search for TestPerson, the RegEx would look like this:
/^(?=.*\bTestPerson).*$/i
This would return both strings, as they both contain TestPerson. If I try and search for $, I get zero results even though both strings contian a $. I know the dollar sign is a special character in RegEx, but escaping it does not work either.
How can I format my RegEx to where searching for $ will return both results?
Thanks!
I think this seems multiline modifier on-off problem. I guess you turned off the multiline modifier and implemented the regex so the unexpected output results. Demo
If you turned on the multiline modifier, you could get the output you want. Demo
To check whether or not a string contains a substring, you don't regex: JavaScript has the string method includes(). This method searches a string for a given value and returns true if it exists in the string and false otherwise.
var a = [
'TestPerson One | 123456789 | ($100.00) | $0 | 03/27/2018 | Open',
'TestPerson Two | 987654321 | ($250.00) | ($25) | 03/27/2018 | Open'
]
a.forEach(function(s) {
console.log(s.includes('TestPerson') && s.includes('$'))
})

How do I select a substring using a regexp in robot framework

In the Robot Framework library called String, there are several keywords that allow us to use a regexp to manipulate a string, but these manipulations don't seem to include selecting a substring from a string.
To clarify, what I intend is to have a price, i.e. € 1234,00 from which I would like to select only the 4 primary digits, meaning I am left with 1234 (which I will convert to an int for use in validation calculations). I have a regexp which will allow me to do that, which is as follows:
(\d+)[\.\,]
If I use Remove String Using Regexp with this regexp I will be left with exactly what I tried to remove. If I use Get Lines Matching Regexp, I will get the entire line rather than just the result I wanted, and if I use Get Regexp Matches I will get the right result except it will be in a list, which I will then have to manipulate again so that doesn't seem optimal.
Did I simply miss the keyword that will allow me to do this or am I forced to write my own custom keyword that will let me do this? I am slightly amazed that this functionality doesn't seem to be available, as this is the first use case I would think of when I think of using a regexp with a string...
You can use the Evaluate keyword to run some python code.
For example:
| Using 'Evaluate' to find a pattern in a string
| | ${string}= | set variable | € 1234,00
| | ${result}= | evaluate | re.search(r'\\d+', '''${string}''').group(0) | re
| | should be equal as strings | ${result} | 1234
Starting with robot framework 2.9 there is a keyword named Get regexp matches, which returns a list of all matches.
For example:
| Using 'Get regexp matches' to find a pattern in a string
| | ${string}= | set variable | € 1234,00
| | ${matches}= | get regexp matches | ${string} | \\d+
| | should be equal as strings | ${matches[0]} | 1234

Regular expression to finding position of a delimiter and remove all except third delimiter notepad++

text example:
ABC | 123 | target | abc.txt |
CDEFG | 12345 | target | [df:ejk] |
need to remove all except the "target"
Below is what the result should look like.
target
target
How can I achieve this?
thanks for help..
I can suggest this regex for Find what field:
(?:[^\n|]*?\|){2}\s*([^\n|]*?)\s*\|[^\n|]*?\|
Replace with $1.
You can replace this
[a-zA-Z]*\s\|\s[0-9]*\s\|\s([a-zA-Z]*)\s\|\s[a-zA-Z\:\.\[\]]*\s\|
by this
\1
To remove all exept third column.

notepad++: keep regex (multi occurence per line) and line structure, remove other characters

I have a 130k line text file with patent information and I just want to keep the dates (regex "[0-9]{4}-[0-9]{2}-[0-9]{2} ") for subsequent work in Excel. For this purpose I need to keep the line structure intact (also blank lines). My main problem is that I can't seem to find a way to identify and keep multiple occurrences of date information in the same line while deleting all other information.
Original file structure:
US20110228428A1 | US | | 7 | 2010-03-19 | SEAGATE TECHNOLOGY LLC
US20120026629A1 | US | | 7 | 2010-07-28 | TDK CORP | US20120127612A1 | US | | EXAMINER | 2010-11-24 | | US20120147501A1 | US | | 2 | 2010-12-09 | SAE MAGNETICS HK LTD,HEADWAY TECHNOLOGIES INC
Desired file structure:
2010-03-19
2010-07-28 2010-11-24 2010-12-09
Thank you for your help!
Search for
.*?(?:([0-9]{4}-[0-9]{2}-[0-9]{2})|$)
And replace with
" $1"
Don't put the quotes, just to show there is a space before the $1. This will also put a space before the first match in a row.
This regex will match as less as possible .*? before it finds either the Date or the end of the row (the $). If a date is found it is stored in $1 because of the brackets around. So as replacement just put a space to separate the found dates and then the found date from $1.

Regex Match and Replace path to file

I am trying to do a regex match and replace for hotfile.com links to mp3 files i have in my database (Wordpress).
I used to use hotfile for streaming mp3 files on my site, now i switched to a CDN, could someone kindly help me out with this:
Replace: http//hotfile.com/dl/157490069/c8732d4/mp3_file_name.mp3
With: http//p.music.cdndomain.com/vod/music.folder/2010/mp3_file_name.mp3
I have been trying a simple Search and Replace like this: http//hotfile.com/dl/%/%/, but its not working.
It would have been easier to perform a search and replace if hotfile.com didn't have different folders for all files, below is 2 examples of the problem:
http//hotfile.com/dl/155490069/c7932d4/
http//hotfile.com/dl/165490070/c8745e7/
I have over 500 files to replace.
Thanks
Since you must be using mysql for your wordpress database, you can do this replacement either by regex as you asked:
Regex pattern : #http://(www.)?hotfile.com/\w+/\w+/\w+/#
Replacement pattern: http//p.music.cdndomain.com/vod/music.folder/2010/
An alternate simpler solution would be to extract the mp3 file name using simple string functions of mysql e.g.
Use SUBSTRING or SUBSTRING_INDEX to extract file name of your mp3 file i.e. find the string after last occurence of "/" in your hotfiles url.
Use CONCAT to append the file name retreived to new url prefix and update it in the database.
Here is an example, you can appropriately change it for your database:
mysql> select * from test_songs;
+---------------------------------------------------------------+
| song_url |
+---------------------------------------------------------------+
| http://hotfile.com/dl/157490069/c8732d4/mp3_file_name.mp3 |
| http://www.hotfile.com/dl/123412312/dd732d4/mp3_song_name.mp3 |
+---------------------------------------------------------------+
Taking substrings:
mysql> select SUBSTRING_INDEX(song_url,"/",-1) from test_songs;
+----------------------------------+
| SUBSTRING_INDEX(song_url,"/",-1) |
+----------------------------------+
| mp3_file_name.mp3 |
| mp3_song_name.mp3 |
+----------------------------------+
2 rows in set (0.03 sec)
Creating final update query:
mysql> Update test_songs set song_url =
CONCAT("http//p.music.cdndomain.com/vod/music.folder/2010/",
SUBSTRING_INDEX(song_url,"/",-1)) ;
Query OK, 2 rows affected (0.00 sec)
Rows matched: 2 Changed: 2 Warnings: 0
Checking the results :
mysql> select * from test_songs;
+---------------------------------------------------------------------+
| song_url |
+---------------------------------------------------------------------+
| http//p.music.cdndomain.com/vod/music.folder/2010/mp3_file_name.mp3 |
| http//p.music.cdndomain.com/vod/music.folder/2010/mp3_song_name.mp3 |
+---------------------------------------------------------------------+
2 rows in set (0.00 sec)
Done !
Something as simple as http://regex101.com/r/lK9wH4 should work:
/^.+\/(.+)$/ and replace with <your_new_url>\1.
Good luck.
you can use notepad++ to search and replace all your files
for this particular sample:
search and replace in regex mode:
search "http//hotfile.com/(.)/(..mp3) "
replace "http//p.music.cdndomain.com/vod/music.folder/2010/\2 "
remove the quote mark but keep the space at the end
