how to automatically write curl output to a new file

问题

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.

Try this:

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

回答2:

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

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

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