QUESTION
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,

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
We are experimenting with Jetbrains Space as our code repo and CI/CD. We are trying to find a way to setup the .space.kts file to deploy to AWS Lambda.
We want the develop branch to publish to the Lambda $Latest and when we merge to the main branch from the develop branch we want it to publish a new Lambda version and link that version to the alias pro.
I've looked around but haven't found anything that would suggest there is a pre-built solution for controlling AWS Lambda so my current thinking is something like this:
...ANSWER
Answered 2021-Jun-15 at 11:09There is no built-in DSL for interacting with AWS.
If you want a solution that is more type-safe than plain shellScript, and maybe reuse data between multiple calls etc, you can still use Kotlin code directly (in a kotlinScript block instead of shellScript).
You can specify maven dependencies for your .space.kts script via the @DependsOn annotation, which you can use for instance to add modules from the AWS Java SDK:

QUESTION
I'm new to Django. I've defined 2 tables and have set a foreign key. So I want to link the column note from table Comment to the column id from table Note.
As I'm using PostgreSQL, when I check the psql shell, the name of the column note will be displayed as note_id.
So for using in template, if I use something like comment.note, it prints the "quick_note" of the note table, which I don't want that. I want to get the "id" of the related post to the current comment, not the quick_note of the related post. But if I use something like comments.note_id, it shows the id of the related post, which is what I expect to get.
Also in the admin panel, I see a field of note: that shows related quick_note not id. How can I fix it that admin panel show the related id? So here I want the id of related post to be shown in front of note:.
This is my model.py:
...ANSWER
Answered 2021-Jun-15 at 06:31This is the behavior of Django, the foreignKey field points to an object while field_id maps to primary key of the object, this important in case of assignment as if you try to save
QUESTION
I am able to do most things inside the dir, but I can't cd out of it, trying /bin/sh causes the shell to freeze.
...ANSWER
Answered 2021-Jun-14 at 22:06Because everytime you send a command a new shell is created in the original folder.
To set an other working directory you have to send cd /to/other/dir && yourcommand
You can try setting the root folder for the new shell terminal:

Install shell
You can use shell like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
