curl-fetch

A recursive bash script that fetches curl using wget which is another UNIX tool to fetch outside binaries and other things.

What is curl-fetch

It's simple, it's a bash script that fetches curl, using wget. It can't get anymore recursive than this. It also has a reversal mode, where you can fetch wget with curl.

Usage

Open up a terminal and run:

chmod +x ./curl_fetch.sh
./curl_fetch.sh # You may want to disable TLS if this fails, just add the --without-ssl conditional. 

If you want TLS, you can select from these conditionals to add:

  --with-amissl
  --with-bearssl
  --with-gnutls
  --with-mbedtls
  --with-mesalink
  --with-nss
  --with-openssl (also works for BoringSSL and libressl)
  --with-rustls
  --with-schannel
  --with-secure-transport
  --with-wolfssl

So say if you pick --with-openssl the command would look like this: ./curl_fetch.sh --with-openssl.

Reversal method

Sometimes fetching curl using wget may not work, in this scenario you'll want to try using wget to fetch curl, then again retrying fetching curl using wget to the latest version:

 # Set the URL for downloading wget
    WGET_URL="https://ftp.gnu.org/gnu/wget/wget-latest.tar.gz"
    WGET_TARBALL="wget.tar.gz"

    if curl -o "${WGET_TARBALL}" "${WGET_URL}"; then
        echo "wget downloaded successfully with curl. The circle is complete."
    else
        echo "Failed to download wget with curl. The irony!"
    fi
}

fetch_wget

Upcoming features in curl-fetch v2.0

• More recursion in the script, so for example:

if wget "${CURL_URL}" -O "${CURL_TARBALL}"; then
        echo "Download complete. But wait, let's download it again for good measure!"
        download_curl
    else
        echo "Error downloading curl. But maybe it'll work if we try again?"
        download_curl
    fi
}
