writing the a local file using parameters on command line

Question

I am trying to write a little project thing to get my javascript skills up. The goal is for, when using curln, the .cmd file will write %~dp0\#temp with the curl %1 (the curled html result of the first parameter)

expected with curln "https://www.google.com": (long html)
actual: "<< was unexpected at this time."

I have tried looking things up, this was a mesh of what I found online. I have tried using < and << as, a beginner, I don't understand the difference.

Code:

%~dp0\#temp << cmd curl %1

I would like the output of curl to be written to the current directory's (%~dp0) file named #temp. %1 is a preset *.cmd parameter variable that is shown in this example: example "this is %1"

> and >> are output. The first creates a new file, the second appends to an existing file. < is input. It accepts input (reads) into a program from another source, which is typically a file or the output of another program. It doesn't work with writing to files.

You're most likely looking for curl %1 >>"%~dp0#temp" instead. You don't need the cmd in front of it, as you're already in a command window when the batch file executes.

@Compo: Corrected. Note that I just used the OP's code directly, changing the order around some. I didn't write the code.

For a simple transfer I use repeatedly using curl the minimal call is

curl -o "%~dpnx0" remote.url

That ensures the fileName and eXtension are saved in the current DrivePath

There is no error checking or security communication so is only useful for a single .html or .js or .pdf etc.

Thus a complex call can run to dozens of lines.
