oneliners | One-line commands | Command Line Interface library

After setting up a GitLab server, GitLab runner CI, and creating a test-repository that completes a CI-job successfully, I was experiencing some difficulties in ensuring a post-receive script is completed after the CI is finished successfully on the test repository commit.

The MWE does the complete deployment, and uploads a repository to the GitLab server and runs the CI on the repository. However, it is not yet generalised well, hence it has (at least) the following requirements: System: Ubuntu 20.04, Architecture:AMD64.

There are a lot of similar questions here on SO (e.g.: How to get different overloads for rvalue and lvalue references with a template-deduced type?), but not exactly this one. In particular, no questions are concered with value returning functions. Furthermore, I am not sure (euphemestically spoken) whether I understood the answers correctly.

I want to provide two versions of a function, which either return a new object or change the passed object (and return the changed object -- for consistency). For simplicity I present my code using a unique like algorithm.

User code

I am using IntelliJ as an IDE. Unfortunately, IntelliJ does not support jq. Language injection is not offered and I can't find a suitable plugin. I searched for "IDE support for jq" or similar many times and surprisingly this brings up nothing useful.

Sometimes I write jq programmes that are not just oneliners. I always struggle with getting the syntax right, for example adding the right amount of brackets in the right place and manually refactoring code into functions is painstaking.

IntelliJ at least offers a hotkey to jump to the matching bracket (Shift-Ctrl-M), which works in any text file and displays the block enclosed by a pair of brackets in colour in the editor.

Are there any special IDE features that make editing jq programs easier? For example, a folding of code blocks based on matching brackets or a bracket selection feature similar to Ctrl-W for selection in Java would be very helpful. Also, it is important for me to indent the jq code properly to make it more understandable. Is there any generic support for formatting code?

I don't expect complete refactorings, but any advice on useful editor features that make life easier as a jq programmer is highly welcome.

Need to manipulate ICS from command line batch script, but did not found suitable console tool. But found powershell script which do such task. The problem is the script is multiline and as I have zero experiences with PS, looking for someone who could create few oneliners from such script to easily run trhough batch script and parse its output. Need following oneliners:

• List adapters with ICS enabled
• Enable ICS for specific interfaces
• Disable ICS on specific interface

Anyone could help me with this?

I have two lists of values, x and y:

I run across this topic once in a while, trying to remember how this was done then find all the incomplete answers again (with config files, oneliners,ignoring that we really want to use a custom CA to create a full certificate chain etc.). And many answers applying SAN for the certificate request, but messing SAN up in the signing command...

What I want to do?

1. Create a custom CA
2. Create a certificate request.
3. Sign the certificate request.
4. Create a chain file
5. Additional steps in Firefox/Chrome (yes, Chrome needs SAN)

(Yes, please don't do everything in one command, I want my CA reside on another machine) (Yes, this might again be incomplete for somebody else. But this is exactly what I need 1-2 times a year, when a simple self-signed cert in my DEV environment, I simply trust by configuration, is not enough) (Yes, you might want to implement additional validation steps, if you are not the one requesting and signing certificates as one person)

I would like to try all the nice oneliners in the documentation of RSpec in the IRB console.

How to execute them in the IRB console?

Please a solution not based in Rails, just plain Ruby.

I am trying print the contents of a column in a file between two regular expressions which are in different columns though. A sample file looks like this
