[linux] How do I get cURL to not show the progress bar?

I'm trying to use cURL in a script and get it to not show the progress bar.

I've tried the -s, -silent, -S, and -quiet options, but none of them work.

Here's a typical command I've tried:

curl -s http://google.com > temp.html

I only get the progress bar when pushing it to a file, so curl -s http://google.com doesn't have a progress bar, but curl -s http://google.com > temp.html does.

Since curl 7.67.0 (2019-11-06) there is --no-progress-meter, which does exactly this, and nothing else. From the man page:

   --no-progress-meter
         Option to switch off the progress meter output without muting or
         otherwise affecting warning and informational messages like  -s,
         --silent does.

         Note  that  this  is the negated option name documented. You can
         thus use --progress-meter to enable the progress meter again.

         See also -v, --verbose and -s, --silent. Added in 7.67.0.

It's available in Ubuntu =20.04 and Debian =11 (Bullseye).

For a bit of history on curl's verbosity options, you can read Daniel Stenberg's blog post.

In curl version 7.22.0 on Ubuntu and 7.24.0 on OSX the solution to not show progress but to show errors is to use both -s (--silent) and -S (--show-error) like so:

curl -sS http://google.com > temp.html

This works for both redirected output > /some/file, piped output | less and outputting directly to the terminal for me.

Update: Since curl 7.67.0 there is a new option --no-progress-meter which does precisely this and nothing else, see clonejo's answer for more details.

On MacOS 10.13.6 (High Sierra), the '-ss' option works. It is especially useful inside perl, in a command like curl -ss --get {someURL}, which frankly is a whole lot more simple than any of the LWP or HTTP wrappers, for just getting a website or webpage's contents.

this could help..

curl 'http://example.com' > /dev/null

Not sure why it's doing that. Try -s with the -o option to set the output file instead of >.

I found that with curl 7.18.2 the download progress bar is not hidden with:

curl -s http://google.com > temp.html

but it is with:

curl -ss http://google.com > temp.html
