Log Parser is great tool for parsing log files. I can parse not just IIS log files but also custom log files with it.
For example I can use SQL syntax to parse logs:
C:\>LogParser "SELECT TimeGenerated, SourceName,
EventCategoryName, Message INTO report.txt FROM Security WHERE
EventID = 528 AND SID LIKE '%TESTUSER%'" -resolveSIDs:ON
Is there any tool like that for linux?
Thanks.

lnav supports SQL queries and supports most of the common Linux log formats. Look at the project's website and documentation page for more details and screenshots.

Maybe you'll take a look at multitail?
When it comes to text based logs grep is your friend—it can do pretty much the same what SQL-like syntax in your example.

have you tired tail command ?
tail -f /path/to/log/file/log
if you prefer a log viewer with GUI, Have a look at
Gnome Log Viewer

I'm trying to migrate content out of one system (Drupal to be specific) into Contentful.
When pulling content out of Drupal, it is formatted in HTML. Putting content into Contentful, it looks like it needs to be in a specific JSON format.
Using NPM package contentful-cli with command contentful space import --content-file import.json
I know there is #contentful/rich-text-html-render but I'm looking for the reverse. Or if there's another strategy that anyone know about to import html into Contentful programmatically...
I have create a basic NPM package contentful-html-rich-text-converter to do this if anyone else runs across this issue. (It is a work in progress, feel free to contribute)
https://www.npmjs.com/package/contentful-html-rich-text-converter
I used turndown to convert to markdown first and then I used #contentful/rich-text-from-markdown to make it to rich text.
It seems to work fine so far.

I am using Spark SQL to do some analysis.
I`m wondering is there any Front end projects can be used to view the result? I mean the analysis result not the job successful / faile status
For example, granafa, kibana, etc..

If you mean visualization of your results (like the ones you've mentioned) you might be interested in Apache Zeppellin. It's more like IPython Notebook so you can write your code there and visualize results.
Otherwise you'd have to tell us what is your storage format and where are you storing your results - maybe there are some visualization tools for it.
Actually if you store your results of Spark jobs in ElasticSearch you can use Kibana with it.
Otherwise, I don't think there is anything. The difference between what you are referring to (openTSDB and Elasticsearch) and Spark is that the latter is not a datastore.

I am a newbie of calabash-android. i did learn how to write scripts for automation testing. please refer me some "books" or "articles" to learn how to write scripts in a optimized way.
I recently started a new job as an automated tester for a mobile app and found the following book a good introduction to the Cucumber framework:
https://pragprog.com/book/hwcuc/the-cucumber-book
It doesn't go into lots of detail about Calabash specifically but does have lots of information on writing tests in general.
Once you have your feature files in place you just write the underlying code (Ruby in my case) to make the app do what you want (ie. touch, swipe).
It's also good to use:
query('*') whilst in the calabash-android console. It dumps out the all the information you need to know for example what ID's and text to check for on any given screen.

I can also settle for a web-based interface, but a good command-line tool is preferable. Now, I have tried to use xsd.exe that comes with mono-devel, but that skipped a whole bunch of stuff that was mentioned in the xml file.
I understand that I will need to hand-tweak the output, but I do want something decent to start with.
Try the tool that comes with the spring framework:

I am looking for a linux api that returns me information about root filesystem.
I can use command stat -f / to get information about root filesystem. Is there any API that returns exactly same information as returned by "stat -f" command ?
statvfs, link goes to a manpage.
Next time when you need to know API than does the same thing like a shell command you can use strace. Like this: strace stat -f / and see what calls do command. On my system it calls statfs64.
