One possible method to acquire the most recent version of curl using a shell script when the exact version is unknown is:

1. Use the command curl --version to check the current version of curl installed on the system.
2. Use the command curl https://curl.haxx.se/download/ | grep -o '/download/curl-[0-9]\.[0-9]\.[0-9]\.tar\.gz' | sort -r | head -n 1 to retrieve the URL of the most recent version of curl from the official download page.
3. Use the command curl -LO <URL> to download the tarball file of the most recent version of curl.
4. Use the command tar -xf curl-*.tar.gz to extract the contents of the tarball file.
5. Use the command cd curl-* to navigate to the directory of the extracted contents.
6. Use the command ./configure && make && sudo make install to compile and install the most recent version of curl.
7. Use the command curl --version again to verify that the installation was successful and the new version is now in use.
