从master切换到master0517的命令：
git checkout master0517
遇到错误commit和push回退：
git reset --hard 98ae6024
git push origin master0517 –force
git add .
git commit –m “”
git push origin master0517
提子系统：
gitcheckout -b master0602
git fetchgit@rnd-isourceb.huawei.com:SUB_NETWORK_PCE/ac_wan_public.gitmaster
git reset --hard FETCH_HEAD
git chreey-pick 7198298372
