When you have multiple servers it pain to remember every configuration and it may take hours to configure servers again incase you need.
\nIt is also impractical to copy each files.<\/p>\n
There are few tools available but they come with overhead attached moreover its fun to write custom solutions \ud83d\ude42<\/p>\n
1. Create directory
\n2. cd into it.
\n3. Initialize git
\n4. Add a remote
\n5. Create branch specifically for that server
\n6. Check out branch
\n7. Add shell script
\n8. Make a commit and push to server.<\/p>\n
