I´m vacation hangover and cannot wrap my head around an Powershell dilemma!
I´ve a script where I get the following output below which is saved to a variable $ScanOutput. Now I want to filter out and only keep the code after ExitCode= (Can be 500 or 0). How can I filter out everything before and after 500 (which can be other codes, not static).
#{StdOut=Checking for updates...
Determining available updates...
Check for updates completed
Number of applicable updates for the current system configuration: 0
No updates available.
Execution completed.
Program exited with return code: 500
; ExitCode=500; StdErr=}
Thanks in advance! Kind regards,
JN
You can simply use Select-String :
($ScanOutput | Select-String -Pattern 'ExitCode=(\d+)').Matches.Groups[1].Value
500
Many ways to skin a cat, assuming the delimiter ; is consistently placed. Might be nice to test which method is fastest:
($scanoutput -split ';')[1].Trim()
ExitCode=500
Since JNilsson came back and said that I actually was correct in my statement that it was hash table I will add back my answer to help others with similar problem.
The object
#{StdOut=Checking for updates... Determining available updates... Check for updates completed Number of applicable updates for the current system configuration: 0 No updates available. Execution completed. Program exited with return code: 500 ; ExitCode=500; StdErr=}
To get the ExitCode from the object simply make sure to assign it to a variable, in my case $hash then you can get the value by doing this:
$hash.ExitCode

I'm trying to print some RFID tags and retrieve their TIDs to store them in my system and know which tags have been printed. Right now I'm reading the TID and sending it back to my computer (connected via USB with the my ZT421 printer) with the following code:
^RFR,H,0,12,2^FN0^FS^FH_^HV0,24,,_0D_0A,L^FS
^RFW,H,2,12,1^FD17171999ABABABAAAAAAAAAB^FS
This is repeated for each tag that I'm printing. However, when printing 10 tags, I only get 9 TIDs. If after that I try to print 7 tags, I still get 9 TIDs. To be honest I'm a bit lost now, because even trying to use the code examples from the ZPL manual (I've tried the ^RI instruction also) it doesn't seem to work.
The communication with the printer is beeing done through Zebra Setup Utilities' direct communication tool.
I tried to retrieve each printed tag TID with:
^RFR,H,0,12,2^FN0^FS^FH_^HV0,24,,_0D_0A,L^FS
^RFW,H,2,12,1^FD17171999ABABABAAAAAAAAAB^FS
but I always get 9 TIDs.
I also tried getting the TID with the ZPL manual example for the ^RI command:
^XA
^FO20,120^A0N,60^FN0^FS
^RI0,,5^FS
^HV0,,Tag ID:^FS
^XZ
And I got absolutely nothing returned to the computer, just a mssage saying "Tag ID:" and no value shown.
I would really appreciate some help with this...
Thanks in advance!
I've fixed the issue, but I'm going to leave the solution here just in case someone else is facing the same problem.
I thought that maybe it wasn't a code issue, but something related to the computer-printer communication. It turned out to be the case. The Zebra Setup Utilities program has a button that says "options". If you click it, a new screen will open and there you can configure the seconds that the program will wait for the printer response (in this case through USB). By default it's set to 5, i changed this value to 100, which is the maximum. This meant that instead of just printing and retrieving the TIDs of 6-9 tags, now I can do it for about 100.
This is not amazing because in my case it implied creating 25 files for the 2500 tags I had to print and store the TIDs, however it's far better than before.
I am facing the issue with for loop execution with logic APP in azure. Apparently complete playbook execute successfully and functionally its working good. However, i am getting this error because it takes "body" parameter from previous step as input and nothing else. The body is long json and therefore should not be the right input for foreach loop. I tried adding account or Ip address as input but that fails as well.
Input
Output
Please help here
As you mentioned there is just one item in your json data array which contains "MachineId", I assume the first item contains "MachineId". Please refer to the solution below, it will help you to use the only "MachineId" in the 24 cycles of your loop.
We can input an expression to use the "MachineId" in first item:
body('Parse_JSON')[0].MachineId
(In the screenshot above, I just use a "Set variable" to replace your two actions in "For each" loop, but I think there is no difference between them)
Please have a try with this solution~
I have defined a variable inside one of the shell script to create the file name with date value in it.
I used "date +%Y%m%d" command to insert the current date which was defined in date_val variable.
And I have defined the filename variable to have "${path}/sample_${date_val}.txt
For few days it was creating the file name properly as /programfiles/sample_20180308.txt
But today the filename was created without date as /programfiles/sample_.txt
When I try to execute the command "date +%Y%m%d" in linux, it is returning the correct value - 20180309.
Any idea why the filename was created without the date value ??? . I did not modify anything in my script too. So wondering what might have gone wrong.
Sample excerpt of my script is given below for easy understanding :
EDITED
path=/programfiles
date_val=$(date +%Y%m%d )
file_name=${path}/sample_${date_val}.txt
Although incredibly unlikely, it's certainly possible for date to fail, based on the source code. Under the covers, it calls either clock_gettime() or gettimeofday(), both of which can fail.
The date program will also refuse to output anything to standard output if the date from either of those two functions is out of range during the call to (which is possible if they fail).
It's also possible that the date program could "disappear" for various reasons, such as actually being hidden or permissions changed, or a shortage of resources like file handles when attempting to open the executable.
As mentioned, all these possibilities are a stretch, unlikely to happen in the real world.
If you want to handle the case where you get inadequate output from date, you can simply try until you get a valid one, something like (with the possibility of adding some limit to detect if it's never any good):
todaysDate="$(date +%Y%m%d)"
while [[ ! $x =~ ^[0-9]{8}$ ]] ; do
sleep 1
todaysDate="$(date +%Y%m%d)"
done
# todaysDate now guaranteed to be eight digits.
I've recently installed arbtt which seems to be an intersting, rule based, automatic time tracker. http://arbtt.nomeata.de/#what
I've got it working for the most part, but after 30 minutes or so of gathering stats, I end up with the following error.
Processing data [=>......................................................................................................................................................................................] 1%
arbtt-stats: Prelude.(!!): index too large
Does anyone have any suggestions on ways I can troubleshoot this issue, or better yet, solve it? I have 0 experience with the coding language used to create the rules (Haskell I believe). All I've done to this point is follow the documentation as closely as possible.
This error ultimately renders the tool useless since it doesn't gather data any longer than 30 minutes. To fix it, I have to delete the log and start from scratch. I'm primarily interested in the notion of having a customizable, rule based time tracker but I'm by no means tied to using arbtt.
Based on the comments below, I'm including some more information below.
When I try to run arbtt-recover I get a long list of errors that look like this. All of them seem to be related to an Unsupported TimeLogEntry.
Trying at position 1726098.
Failed to read value at position 1726098:
Unsupported TimeLogEntry version tag 0
As for the configuration file, here is what I have so far.
$idle > 30 ==> tag inactive,
-- A rule that matches on a list of strings
current window $program == ["Chrome", "Firefox"] ==> tag Web,
current window $program == ["skype"] ==> tag Skype,
current window $program == ["jetbrains-phpstorm"] ==> tag PhpStorm,
( current window $title =~ m!Inbox! ||
current window $title =~ m!Outlook! ) ==> tag Emails,
( current window $title =~ m!AdWords! ||
current window $title =~ m!Analytics! ) ==> tag Adwords,
It goes on further, but I'm fairly confident I've followed this same syntax for all other lines. The rest of the lines are following the same format but are project/client specific for me. If required, I'm happy to include the rest of the file.
As discussed in the comments: This is a case of a corrupt ~/.arbtt/capture.log. You can usually fix this by
running arbtt-recover
and then moving ~/.arbtt/capture.log.recovered to ~/.arbtt/capture.log.
The second manual step is required to avoid accidentially deleting too much data. You can test that the recovered file is better by making arbtt-stats using the recovered file by passing --logfile=~/.arbtt/capture.log.recovered to it.
Data corruption happens for example when there is an unclean shutdown, or other undetermined reasons. But the log file format is such that even after a corruption (e.g. a partial write of one sample), further samples will be written correctly and should be picked up by arbtt-recover, so you did not lose more than a few samples.
I am using Cucumber with RubyMine, and I have a scenario with steps that verify some special controls from a form (I am using cucumber for automation testing). The controls don't have anything to do with each other, and there is no reason for the steps to be skipped if one in front of them fails.
Does anyone know what configurations or commands should I use to run all the steps in a scenario even if they all fail?
I think the only way to achieve desired behavior (which is quite uncommon) is to define custom steps and catch exceptions in it yourself. According to cucumber wiki step is failed if it raises an error. Almost all default steps raise error if they can't find or interact with an element on the page. If you'll catch this exceptions the step will be marked as passed, but in rescue you can provide custom output. Also I recommend you to carefully define exceptions you want to catch, I think if you're Ok if selenium can't find an element on the page rescue only from ElementNotFound exceptions, don't catch all exceptions.
I've seen a lot of threads on the Web about people wanting to continue steps execution if one failed.
I've discussed with Cucumber developers: they think this is a bad idea: https://groups.google.com/forum/#!topic/cukes/xTqSyR1qvSc
Many times, scenarios can be reworked to avoid this need: scenarios must be split into several smaller and independent scenarios, or several checks can be aggregated into one, providing a more human scenario and a less script-like scenario.
But if you REALLY need this feature, like our project do, we've done a fork of Cucumber-JVM.
This fork let you annotate steps so that when they fail with a determined exception, they will let let next steps execute anyway (and the step itself is marked as failed).
The fork is available here:
https://github.com/slaout/cucumber-jvm/tree/continue-next-steps-for-exceptions-1.2.4
It's published on the OSSRH Maven repository.
See the README.md for usage, explanation screenshot and Maven dependency.
It's only available for the Java language, tough: any help is welcome to adapt the code to Ruby, for instance. I don't think it will be a lot of work.
The question is old, but hopefully this will be helpful. What I'm doing feels kind of "wrong", but it works. In your web steps, if you want to keep going, you have to catch exceptions. I'm doing that primarily to add helpful failure messages. I'm checking a table full of values that are identified in Cucumber with a table having a bunch of rows like:
Then my result should be:
| Row Identifier | Column Identifier | Subcolum Identifier | $1,247.50 |
where the identifiers make sense in the application domain, and name a specific cell in the results table in a human-friendly way. I have helpers that convert the human identifiers to DOM IDs, which are used to first check whether the row I'm looking for exists at all, then look for the specific value in a cell in that row. The default failure message for a missing row is clear enough for me (expected to find css "tr#my_specific_dom_id" but there were no matches). But the failure message for checking specific text in a cell is completely unhelpful. So I made a step that catches the exception and uses the Cucumber step info and some element searching to get a good failure message:
Then /^my application domain results should be:$/ do |table|
table.rows.each do |row|
row_id = dom_id_for(row[0])
cell_id = dom_id_for(row[0], row[1], row[2])
page.should have_css "tr##{row_id}"
begin
page.should have_xpath("//td[#id='#{cell_id}'][text()=\"#{row[3].strip.lstrip}\"]")
rescue Capybara::ExpectationNotMet => exception
# find returns a Capybara::Element, native returns a Selenium::WebDriver::Element
contents = find(:xpath, "//td[#id='#{cell_id}']").native.text
puts "Expected #{ row[3] } for #{ row[0,2].join(' ') } but found #{ contents } instead."
#step_failures_were_rescued = true
end
end
end
Then I define a hook in features/support/hooks.rb like:
After do |scenario|
unless scenario.failed?
raise Capybara::ExpectationNotMet if #step_failures_were_rescued
end
end
This makes the overall scenario fail, but it masks the step failure from Cucumber, so all the step results are green, including the ones that aren't right. You have to see the scenario failure, then look back at the messages to see what failed. This seems kind of "bad" to me, but it works. It's WAY more convenient in my case to get the expected and found values listed in a domain-friendly context for the whole table I'm checking, rather than to get a message like "I looked for "$123.45" but I couldn't find it." There might be a better way to do this using the Capybara "within" method. This is the best I've come up with so far though.
