This isn’t a complete list nor is it a best of list. This is just a list of what i’ve found and use.

Another one of my favorite commands I use often. I usually do this before I run rubocop or when I push to github before I do a pull request.

git diff master --name-only

In my .zshrc I have an alias:

alias gdfiles="git diff master --name-only"

 

I usually add an alias in my .zshrc file so that I can run a single command to clean up feature branches that are merged into master or develop.

alias gbclean="git branch --merged | egrep -v '(^\*|master|develop)' | xargs git branch -d"

But if you run:

git branch --merged | egrep -v '(^\*|master|develop)' | xargs git branch -d

This will remove all branches that are merged into master or develop.

Most new laptops/computers come with multiple cores standard.

So assuming you do have a system with multiple cores why not use them.

# How many cores are on your system?
> sysctl -n hw.ncpu
24
> bundle config --global jobs 24

* This might work on any *nix system just find the appropriate commands.

Ever run “gem list rails -r” just to get a list of all gems with “rails” in it. When you were just wondering what’s the latest version of rails on the remote server is.

gem list -r | grep -i "^rails "

This will get your what you want.
