I think what you are looking for is this: 我认为您正在寻找的是:
wget --output-document=/dev/null https://www.ziffi.com/suggestadoc/js/ds.ziffi.https.v307.js 2>&1 >/dev/null | grep = | awk '{print $5}' | sed 's/^.*\=//'
Explanation: 说明:
2>&1 >/dev/null | 2>&1> / dev / null | --> Makes sure stderr gets piped instead of stdout ->确保用stderr代替标准输出
grep = --> select the line that contains the '=' symbol grep = ->选择包含'='符号的行
sed 's/^.*\\=//' --> deletes everything from linestart to the = symbol sed's /^.*\\=//'- >删除从linestart到=符号的所有内容
