检查this gist是否有帮助，至少对于chromedriver：

version=$(curl http://chromedriver.storage.googleapis.com/LATEST_RELEASE)
download_location= " http://chromedriver.storage.googleapis.com/ $version /chromedriver_linux64.zip "
rm /tmp/chromedriver_linux64.zip
wget -P /tmp $download_location
unzip /tmp/chromedriver_linux64.zip -d .
mv ./chromedriver ./chromedriver.linux
chmod u+x ./chromedriver.linux

关于geckodriver：

install_dir= " /usr/local/bin "
json= $( curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest )
if [[ $( uname )  ==  " Darwin " ]] ;  then
url= $( echo " $json "  | jq -r ' .assets[].browser_download_url | select(contains("maces")) ' )
elif [[ $( uname )  ==  " Linux " ]] ;  then
url= $( echo " $json "  | jq -r ' .assets[].browser_download_url | select(contains("linux64")) ' )
else
 echo  " can't determine OS "
 exit 1
fi
curl -s -L " $url "  | tar -xz
chmod +x geckodriver
sudo mv geckodriver " $install_dir "

要避免两个结果（.tar.gz和.tar.gz.asc文件）：

https://github.com/mozilla/geckodriver/releases/download/v0.33.0/geckodriver-v0.33.0-linux64.tar.gz
https://github.com/mozilla/geckodriver/releases/download/v0.33.0/geckodriver-v0.33.0-linux64.tar.gz.asc

字符串
我需要在jq命令的末尾添加一个新的select子句。
示例如下：

curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest | jq -r ' .assets[].browser_download_url | select(contains("linux64")) | select(endswith("tar.gz"))'

型
这只会选择所需的URL（.tar.gz存档URL）：

https://github.com/mozilla/geckodriver/releases/download/v0.33.0/geckodriver-v0.33.0-linux64.tar.gz
