how to automatically write curl output to a new file

Question

I am using cURL to retrieve stock information back to the terminal window on my Mac using the yahoo finance api.

i.e. I type:

curl -s 'http://download.finance.yahoo.com/d/quotes.csv?s=aapl&f=l1'

and it prints the output (in this instance the last trade price in the command line)

It works terrific, but I would like to know how to get this output automatically written to a stock.txt file located on my desktop without any manual intervention upon the execution of the original cURL command.

Thus after I type the curl query that contains the stock ticker, I get the value written in the terminal window and the txt file.

Hi, the "curl -s..." command no longer works, do you know what the updated url is? — Brajesh

Try this:

curl -s 'http://download.finance.yahoo.com/d/quotes.csv?s=aapl&f=l1' > ~/Desktop/stock.txt && more ~/Desktop/stock.txt

the && more, just for my knowledge what is this doing

The && more command tells the shell to wait until output is complete to ~/Desktop/stock.txt, and then to open it up using the command more (which just views a file). The solution below uses the tee command which does this in one step.

You could use curl ... | tee ~/Desktop/stock.txt

There is also the -o/--output option:

curl -o users.json https://reqres.in/api/users
