kandi X-RAY | Shell Summary
here is a detailed information about the scripts i have written. i do not consider myself a programmer, i create these little programs as experiments to have a play with the language, or to solve a problem for myself. i would gladly accept pointers from others to improve the code and make it more efficient, or simplify the code. if you would like to make any comments then please feel free to email me at craig@geekcomputers.co.uk. in the scripts the comments etc are lined up correctly when they are viewed in notepad++ or vi. this is what i use to code shell scripts. arch_check.ksh - this script checks the archive location for any log files that have not yet been compressed and compresses them. backup.ksh - backup script for root disk. batch_file_rename.sh - this will batch rename all files from one extension to another. check_alert_log.sh - start/stop the perl script to monitor the oracle alert log. check_oracle.ksh - this script checks the pmon and the listener processes are running on the server. coalesce.ksh - this script gets the list of the tablespaces within the database and then coalesces them. create_me.ksh - i use this to create me on new solaris

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,
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
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:
