Command line – Microsoft Task Scheduler: Schtasks.exe can not register new task in Arabic operating system (locale)

I created a task in the MS Task Scheduler app with the simple XML command approach:

"C: TEST.xml"

When I try to register the task in an Arabic regional operating system setting / machine, task registration fails.

Failed command_prompt (image)

XML (task):


However, if I edit the date in this XML file in our default calendar 2019 (en-US based) instead of the Arabic year 1441 (Hijri calendar), the task is successfully registered:

Success command_prompt (image)


I am using this command from a Wpf UI application, so I can not put an unlocated date format in it. Please let me know how I can register this task on this localized computer! Many thanks.

Select a single line based on a condition

Hii Consider the following table structure

table structure

 Table "public.studenttable"
 Column  |  Type   | Modifiers 
 id      | integer | not null
 uid     | text    | not null
 subject | text    | 
    "studenttable_pkey" PRIMARY KEY, btree (id, uid)

Select * from the student table

 id | uid | subject 
  1 | S01 | Maths
  1 | S02 | Science
  1 | S03 | English
  2 | S02 | English

My goal is to get lines that only have English as the topic to return id = 2 row only, I have the following approaches in mind

  1. Return Subjects as a semicolon-delimited string for a specific ID and loop to assign violations.

Select id, (array_agg (subject), & # 39 ;; & # 39;) from the student table by ID

  1. The second approach is to self-associate with studenttable to ensure this id = 1 has only one topic.

I can not ask the final request. Is there an alternative?

Command Line Terminal will not start up in Double Commander after upgrading to Catalina 10.15.1

I just upgraded to Catalina 10.15.1 and had problems opening the Double Commander terminal

When I click on the terminal button that corresponds to these actions:
Enter image description here

Now the terminal is no longer displayed

Even if I press shift+enter suppose to open the terminal in the current dir I got this error

/var/tmp/doublecmd-Xwwn: line 5: /Users/A/.yarn: is a directory
Saving session...

And F9 does not work either.
I am on DC 0.9.6 beta.

Any ideas?

Command line – The flask shell does not open in ipython in pycharm

I'm working on a piston application in pycharm. I used to be able to open the bottle case in the Ipython console. But I messed up Python in my system and had to reinstall Python3.

Since then, I can not open the Flask shell in the Ipython console anymore. It will open in the default python console instead.
What can be wrong with my Ubuntu environment?

typescript – TSLint: expression has the type "void". Put it as an instruction in a separate line

When I run firebase deploy The CLI app runs the TS compiler and TSLint triggers the error shown in the commented line:

express.get("/shopify/callback", async (req: Request, res: Response): Promise => {
 const {shop, code, state} = req.query;

 // parse the cookie string into an array. if state cookie is "", err
 const stateCookie = cookie.parse(req.headers.cookie as string || "").state;
 if (!stateCookie) return res.status(400).send("No state cookie");

 if (state !== stateCookie) return res.status(403).send('Cookie failed verification');

 const {hmac, ...params} = req.query;
 const queryParams = queryString.stringify(params);
 const hash = generateEncryptedHash(queryParams); // ERROR: /home/owner/PhpstormProjects/shopify/projectName/functions/src/index.ts:157:15 - Expression has type `void`. Put it on its own line as a statement.
 if (hash !== hmac) return res.status(400).send("HMAC validation failed");

I do not understand what change is desired. Does anyone know how to handle this error? Here's the helper function that runs in this line:

const generateEncryptedHash = (params: unknown) => {
 if (typeof  SHOPIFY_API_SECRET === "string") {
  crypto.createHmac("sha256", SHOPIFY_API_SECRET).update(params as DataView).digest('hex');
 } else {
  throw Error("during generateEncryptedHash() SHOPIFY_API_SECRET was not a string")

The complete terminal error output is below:

Command Line – How to get a list of folders and number files in each folder next to each other in the current directory?

I am in the directory:
and under the directory are 100 folders:


Which command would I use to print the list of folders and the number of files of each next to each other. Something like that:

folder1     25
folder2     78
folder3     34
folder100   88

I am sure that this is something fundamental, but I could not find a good answer …
