我想把test.txt里面b：下面一行的1替换成0，怎么写啊？
sed -i "s/1/0/g" test.txt
记得备份
sed -i :a;N;$!ba;s/b: 1/b: 0/ test.txt
最多设置5个标签!
{var%20f='http://v.t.sina.com.cn/share/share.php?appkey=1515056452',u=z||d.location,p=['&url=',e(u),'&title=',e(t||d.title),'&source=',e(r),'&sourceUrl=',e(l),'&content=',c||'gb2312','&pic=',e(p||'')].join('');function%20a(){if(!window.open([f,p].join(''),'mb',['toolbar=0,status=0,resizable=1,width=440,height=430,left=',(s.width-440)/2,',top=',(s.height-430)/2].join('')))u.href=[f,p].join('');};if(/Firefox/.test(navigator.userAgent))setTimeout(a,0);else%20a();})(screen,document,encodeURIComponent,'','','https://wenda.whatsns.com/data/attach/logo/logo.png', '推荐 pangxiediyiren 的问题《linux文本替换命令，救救小白。。》','https://wenda.whatsns.com/q-302831.html','页面编码gb2312|utf-8默认gb2312'));){kind=link}
付费偷看金额在0.1-10元之间
sed -i "s/1/0/g" test.txt
记得备份
sed -i :a;N;$!ba;s/b: 1/b: 0/ test.txt
