I have a text document that contains a bunch of URLs in this format:

URL = "sitehere.com"

What I'm looking to do is to run curl -K myfile.txt, and get the output of the response cURL returns, into a file.

How can I do this?

curl -K myconfig.txt -o output.txt 

Writes the first output received in the file you specify (overwrites if an old one exists).

curl -K myconfig.txt >> output.txt

Appends all output you receive to the specified file.

Note: The -K is optional.

For a single file you can use -O instead of -o filename to use the last segment of the URL path as the filename. Example:

curl -O

will save the results to a new file named big-file.iso in the current folder. In this way it works similar to wget but allows you to specify other curl options that are not available when using wget.

There are several options to make curl output to a file

 # saves it to myfile.txt
curl -o myfile.txt
# The #1 will get substituted with the url, so the filename contains the url
curl -o "file_#1.txt"
# saves to data.txt, the filename extracted from the URL
curl -O
# saves to filename determined by the Content-Disposition header sent by the server.
curl -O -J 

Either curl or wget can be used in this case. All 3 of these commands do the same thing, downloading the file at and saving it locally into "my_file.txt":

wget -O my_file.txt # my favorite--it has a progress bar
curl -o my_file.txt
curl > my_file.txt

Notice the first one's -O is the capital letter "O".

The nice thing about the wget command is it shows a nice progress bar.

You can prove the files downloaded by each of the 3 techniques above are exactly identical by comparing their sha512 hashes. Running sha512sum my_file.txt after running each of the commands above, and comparing the results, reveals all 3 files to have the exact same sha hashes (sha sums), meaning the files are exactly identical, byte-for-byte.

For those of you want to copy the cURL output in the clipboard instead of outputting to a file, you can use pbcopy by using the pipe | after the cURL command.

Example: curl | pbcopy. This will copy all the content from the given URL to your clipboard.

Linux version: curl | xclip

Windows version: curl | clip

Use --trace-ascii output.txt to output the curl details to the file output.txt.

If you want to store your output into your desktop, follow the below command using post command in git bash.It worked for me.

curl --request POST --header "Content-Type: application/json" -o "C:\Desktop\test.txt"

A tad bit late, but I think the OP was looking for something like:

curl -K myfile.txt --trace-ascii output.txt

You need to add quotation marks between "URL" -o "file_output" otherwise, curl doesn't recognize the URL or the text file name.

Format

curl "url" -o filename

Example

curl "" -o output_file.txt

Example_2

curl "" > output_file.txt 

Just make sure to add quotation marks.

Writes the first output received in the file you specify (overwrites if an old one exists).

curl -K myconfig.txt >> output.txt
