Linux
Debian-based systems i.e. Ubuntu have update-alternatives, a system that maintains symbolic links to default commands
From the man page:
EXAMPLES
There are several packages which provide a text editor compatible with vi, for example nvi and vim.
Which one is used is controlled by the link group vi, which includes links for the program itself
Typing vagrant from the command line will display a list of all available commands.
Be sure that you are in the same directory as the Vagrantfile when running these commands!
vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)

| /* Some clients do not support PUT or it’s difficult to send in a PUT request. For these cases, you could POST the request with a request header of X-HTTP-Method-Override set to PUT. What this tells the server is that the intended request is a PUT. Obviously this relies on the API you are accessing making use of the X-HTTP-Method-Override Header.*/ |
Unless you are using Safari on OSX, most browsers will have some kind of free plugin that you can use to export the browser's history. So that's probably the easiest way. The harder way, which seems to be what Safari wants is a bit more hacky but it will also work for other browsers. Turns out that most of them, including Safari, have their history saved in some kind of sqlite database file somewhere in your home directory.
The OSX Finder cheats a little bit and doesn't show us all the files that actually exist on our drive. It tries to protect us from ourselves by hiding some system and application-specific files. You can work around this by either using the terminal (my preferred method) or by using the Cmd+Shft+G in Finder.
Once you locate the file containing the browser's history, copy it to make a backup just in case we screw up.
