I see that jq can calculate addition as simply as jq 'map(.duration) | add' but I've got a more complex command and I can't figure out how to perform this add at the end of it.
I'm starting with data like this:
...ANSWER
Answered 2021-Jun-15 at 22:54If any of your output is going to be raw, you need to pass -r; it'll just be ignored for data items that aren't strings.
Anyhow -- if you write (expr1, expr2), then your input will be passed through both expressions. Thus:
QUESTION
Or, more specifically, does it use the default shell, or actually running the actual file. Example: system("echo Hello, World!"). Would this run using, lets say Bash, or would this run by telling to kernal to run a command? Also, is this on topic, or would this fit better somewhere else?
ANSWER
Answered 2021-Jun-15 at 21:28man system is your friend here. This is what is says on my system:
The system() library function uses fork(2) to create a child process that executes the shell command specified in command using execl(3) as follows:

Ansible 2.11.0
I have a shell script that accepts 2 parameters that I want to run on a Windows host, but want to run it inside git-bash.exe. I've tried this,
ANSWER
Answered 2021-Jun-15 at 17:47be aware I don't have a Windows machine against which to try this, so it's just "best effort"
As best I can tell, your problem is because you are trying to recreate the behavior of win_shell by "manually" invoking that improperly quoted cmd.exe /c business, ending up with cmd.exe /c "cmd.exe /c whatever"; dialing up the ansible verbosity -vv could confirm or deny that pattern
Also, the win_shell docs say to use win_command: unless you have a shell redirect need, which as written your task does not.

QUESTION
I am trying to run a simple parallel program on a SLURM cluster (4x raspberry Pi 3) but I have no success. I have been reading about it, but I just cannot get it to work. The problem is as follows:
I have a Python program named remove_duplicates_in_scraped_data.py. This program is executed on a single node (node=1xraspberry pi) and inside the program there is a multiprocessing loop section that looks something like:
...ANSWER
Answered 2021-Jun-15 at 06:17Pythons multiprocessing package is limited to shared memory parallelization. It spawns new processes that all have access to the main memory of a single machine.
You cannot simply scale out such a software onto multiple nodes. As the different machines do not have a shared memory that they can access.
To run your program on multiple nodes at once, you should have a look into MPI (Message Passing Interface). There is also a python package for that.
Depending on your task, it may also be suitable to run the program 4 times (so one job per node) and have it work on a subset of the data. It is often the simpler approach, but not always possible.
QUESTION
There are more than 6k JSON files, each containing exactly one JSON object. I want to prepare one list of objects from these JSONs.
When I am running below jq command I am getting an error.
ANSWER
Answered 2021-Jun-14 at 22:04This is a job that xargs is created to fix -- splitting lists of items into individual command lines that are within the permitted limit.
Because running jq -s a single time is different from concatenating the results of multiple smaller runs, it's appropriate to use xargs to combine cat invocations using the manner described in the linked duplicate.

Install bash
You can use bash like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the bash component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
