I wanted to get the strings inside the ( ) parenthesis but im not sure what KQL function to do it.
123 (SuperLongText) - Repeatative Suffix
12345 (SuperLongText) - Repeatative Suffix
3213 (ShortText) - Repeatative Suffix
parse operator is probably what you want to use here:
| parse InputText with * "(" superLongText ") -" *
| project InputText, superLongText
You can try something below
substring("123 (SuperLongText)"
, indexof("123 (SuperLongText)","(")
, indexof("123 (SuperLongText)",")") - indexof("123 (SuperLongText)","(")
)

I am not getting any output if I am doing this.
mac_address=abcd
output=net_connect.send_command('show mac-address-table | inc mac_address')
print("Output of the switch ",output)
I am getting the desired output if I am doing this.
output=net_connect.send_command('show mac-address-table | inc abcd')
print("Output of the switch ",output)
What should I make change in the code so that I can use variable?
The closing quote in the first example is after mac_address, making that literal text, not a variable. I'm not sure how you append two strings, but something like:
output=net_connect.send_command('show mac-address-table | inc '+mac_address)
where the + is appending the literal string and the variable string.
I have a key/value below in a JSON
JAVA_OPTS="JAVA_OPTS": "-Xms1g -Xmx2g -Dapi.version=v1 -Dspring.profiles.active=test -Dservice.name=xyz"
Using jq i want to insert one more string to this key/value pair "-Dhttps.protocols=TLSv1.2"
So the output should looks like
JAVA_OPTS="JAVA_OPTS": "-Xms1g -Xmx2g -Dapi.version=v1 -Dspring.profiles.active=test -Dservice.name=xyz -Dhttps.protocols=TLSv1.2"
You might be looking for something like that :
jq '.JAVA_OPTS |= . + " -Dhttps.protocols=TLSv1.2"'
Try it here.
I have a string in a data frame as: "(1)+(2)"
I want to split with delimiter "+" such that I get one element as (1) and other as (2), hence preserving the parentheses. I used strsplit but it does not preserve the parenthesis.
Use
strsplit("(1)+(2)", "\\+")
or
strsplit("(1)+(2)", "+", fixed = TRUE)
The idea of using strsplit("(1)+(2)", "+") doesn't work since unless specified otherwise, the split argument is a regular expression, and the + character is special in regex. Other characters that also need extra care are

Below Worked for me:
import re
re.split('\\+', 'ABC+CDE')
Output:
['ABC', 'CDE']
We are working with Apache Tomcat 7 and trying to setup the Valve Component to store our access logs, ready for processing in SnowPlow.
The problem we have is how to make these logs robust. To give an example - we can separate fields with tabs and extract the user agent string like so:
pattern="%{yyyy-MM-dd}t %{hh:mm:ss}t %{User-Agent}i "
The problem is that the Valve Component does not (as far as I can see) escape %{User-Agent}i, so a stray tab in a useragent will corrupt the data (row will look like it contains four fields, not three).
As far as solutions, unless there's a way of escaping the useragent which I've missed, I can see a couple of solutions:
Use a really obscure field delimiter (or combination of field delimiters) which is very unlikely to crop up in a useragent string. We tried Ctrl-A (HTML ?) but that didn't seem to work
Write a custom AccessLogValve which either supports escaping or sanitizes tabs - perhaps similar to this post Sanitizing Tomcat access log entries
A bit puzzled that I can't find anything else about this online - does nobody parse their Tomcat access logs?
What do you recommend? We're a little stuck...
RFC2616 defines user agent string as
User-Agent = "User-Agent" ":" 1*( product | comment )
Then product is defined as
product = token ["/" product-version]
product-version = token
Following this, tokens are defined as
token = 1*<any CHAR except CTLs or separators>
and separators/CTLs as
separators = "(" | ")" | "<" | ">" | "#"
| "," | ";" | ":" | "\" | <">
| "/" | "[" | "]" | "?" | "="
| "{" | "}" | SP | HT
CTL = <any US-ASCII control character
(octets 0 - 31) and DEL (127)>
We need not to forget comment, which is defined as
comment = "(" *( ctext | quoted-pair | comment ) ")"
ctext = <any TEXT excluding "(" and ")">
quoted-pair = "\" CHAR
CHAR = <any US-ASCII character (octets 0 - 127)>
So if I understand correctly, you should be able to use any separator or CTL as long as you can distinguish comment, which is wrapped in ( and ). If ( appears inside the comment, it should be escaped with \.
In the end, I wrote a custom Tomcat AccessLogValve which:
Introduced a new pattern, 'I', to escape an incoming header
Introduced a new pattern, 'C', to fetch a cookie stored on the response
Re-implemented the pattern 'i' to ensure that "" (empty string) is replaced with "-"
Re-implemented the pattern 'q' to remove the "?" and ensure "" (empty string) is replaced with "-"
Overwrote the 'v' pattern, to write the version of this AccessLogValve, rather than the local server name
It seems to be pretty robust - I haven't had any further issues with unescaped values.
I am not able to get the same output as the example given in the SED tutorial for branching below,
http://www.grymoire.com/Unix/Sed.html#uh-59
Quoting the code here:
#!/bin/sh
sed '
:again
s/([ ^I]*)//
t again
'
The spaces are still in the brackets after this filter.
[UPDATE]
Here is my output:
$echo "( ( test ) )" | sed '
> :again
> s/([ ]*)//
> t again
> '
( ( test ) )
$
Shouldn't that be ((test))?
How do I get the script to delete the blank spaces in the nested parenthesis as demonstrated by the author?
[/UPDATE]
[UPDATE2]
$echo " ( ( ) ) " | sed '
> :again
> s/\([ ]*\)//
> t again
> '
Prompt is not back.
[/UPDATE2]
Also how do I enter the "^I" character? I think it is the horizontal tab, but I am not able to key in like other control characters via puTTY(for eg, to get "Enter", I type "Ctrl-V" followed by the "Enter" key, but this isn't working for tab). I tried with spaces only(using regex [ ]* instead of [ ^I]*), but this also failed to work.
Bully for you to work thru some tutorials.
Assuming you're using vi or vim all you need to do to include a tab char inside the [ .. ] grouping, is to type the tab key. ( I use putty all the time, and if pressing tab char doesn't "insert" a tab char into document/command-line, then you have a putty configuration problem ).
The ^I is from the vi list mode. List mode is handy to see where are line-feed chars (\n) will show as the reg-exp char $ (which in reg-ex is an "end-of-line anchor", the other being ^ char (beginning of line)).
So turning on vi list mode, with :li and you'll see all tab chars expanded as ^I and all end of lines as $
As you say
How do I get the script to delete the blank spaces in the nested parenthesis as demonstrated
That is slightly ambiguous, as newer seds use plain parens as grouping chars to create replacement group like \1 for the replacement-side of the s/pat/repl/ substitute cmd.
Given that your example has no numbered-replacement value in the replacement-side, I'll assume that the purpose is the remove a literal () pair AND that it should work as indicated. Once you :set list, add a tab-char inside the [ ... ], it should work. If not, please edit your question with any error messages that might appear.
I hope this helps.
( test ) does not match the regex ([ ]*). ([ ]*) only matches strings that contain nothing but spaces inside parens. Perhaps you are looking for ([ ]* to remove leading spaces inside and [ ]*) to remove trailing spaces.
