There are some steps in there that we should just be doing all the time. What about making a single command alias that will cycle through all these commands just so we know things are always in good shape? Yup, we can do that.
Using Git and Bash is like using a zipper and pants. They just go together. Creating a Bash alias is extremely simple. From your Terminal, enter
$ open ~/.bash_profile
This will open a hidden file in a default text editor. If you have a shortcut command for opening in an editor like Sublime Text, use that to open the file. In the file add the following:
alias refresh="git checkout master && dskil && git pull && git fetch -p"
The alias dskil is useful for removing annoying .DS_Store files. You should have a .gitignore file that keeps these out of version control, but I like to keep a clean house too. To make that work, add the following:
alias dskil="find . -name '*.DS_Store' -type f -delete"
With this in your .bash_profile, you simply need to enter refresh in the command line and POW!
If you are on Windows and using Powershell, you can use the same aliases, but the set up is different. The article Windows PowerShell Aliases is a good tutorial of the process.
