Usr Folder Mac Os X. R For Mac
Is there a manual or guide to what all of the built-in directories should be used for? Like what is /home/, or /net/? Take a look at the for the most up-to-date information and at man hier in Terminal, which provides a 'historical sketch' of the filesystem hierarchy (it's included at the end of this answer for reference). A comment to your question mentions the. You will probably come to the conclusion, after perusing and man hier, that macOS doesn't follow the, that's more of a Linux thing.
Of course, there are similarities between the FHS and the filesystem layout in macOS because of the common UNIX origin, but the differences are striking. MacOS doesn't use any of these:. /boot folder - macOS uses /System/Library/Kernels instead (in older versions of macOS, the folder containing the kernel was /). /home folder - macOS uses /Users instead. /root folder - macOS uses /var/root instead and /opt isn't mentioned not one time in any document (more on /opt below.) A further distiction between macOS and a FHS-compliant OS is the use of /private, for example /etc is a to /private/etc.
About /net: It is an automounter map (listed in /etc/automaster), see for more information. What does and should go into /opt/ and what should/does go into /usr/? My understanding is that /usr/ used to be for user home directories, but since that exists in /Users/ - what is the purpose now? Although /usr, that's no longer the case. Nowadays, /usr contains user commands (in /usr/bin for normal users and /usr/sbin for administrative users, like root), shared libraries ( /usr/lib), man pages ( /usr/share/man), executables that shouldn't be run directly by users ( /usr/libexec) and other stuff. It also offers a subdirectory, /usr/local, to place programs, libraries and other files that don't come with the base OS.
/opt has a very similar role to /usr/local and they seem interchangeable. However, from my experience working with other Linux/UNIX sysadmins, there seems to be a preference for /usr/local in BSD-based UNIX OSs. So this is my take on it: macOS is BSD-based and consequently I'd use /usr/local. Note that you can create a program directory and then symlink commands to /usr/local/bin, etc, for example: /usr/local/mysql /usr/local/mysql/bin/mysqladmin /usr/local/mysql/lib/libmysqlclient.so /usr/local/bin/mysqladmin -./mysql/bin/mysqladmin /usr/local/lib/libmysqlclient.so -./mysql/lib/libmysqlclient.so This used to be usual practice in Linux and UNIX too, but the FHS it: if you wish to install third party packages in their own directory hierarchy you should use /opt/ instead. Note that FHS-compliance requires to put configuration files in /etc/opt/ and variable files in /var/opt/. So, in macOS, I'd recommend that you stick to /usr/local as described above.

I'm aware of add-on software like Cisco VPN and that install in /opt, so the above distinctions start to blur. Man hier As mentioned above this is man hier: A historical sketch of the filesystem hierarchy. The modern macOS filesystem is documented in the ``File System Programming Guide' available on Apple Developer. / root directory of the filesystem /bin/ user utilities fundamental to both single-user and multi-user environments /dev/ block and character device files fd/ file descriptor files; see fd(4) /etc/ system configuration files and scripts /machkernel kernel executable (the operating system loaded into memory at boot time). When I read of /opt (often ) and of 'standard' uses of paths, I think also of.

Hi there, I'm a bit of a Mac n00b as well as a R-Studio one so this is hopefully easy to help with:) I have two user logins for my Mac - one for work and one for home (admin). I've installed RStudio and it works great on the home (admin) profile but when I try to launch via the work profile I get a start up error 'The R Session failed to start', despite being able to access normal R GUI (version 2.14.2) fine in the work profile. I think I want to give sudo access to the RStudio so it works on all profiles, but can't find a way to do this. Perhaps via terminal but I'd prefer to launch as other applications, which don't seem to have the same trouble. I've given the R package read and write access for everyone, no effect.
Hope you can help:) Best wishes, Mark. Hi Josh, thanks for the aid / here is the output. Total 1232 drwxr-xr-x 34 markedmondson staff 1156 16 Oct 16:31. Drwxr-xr-x 6 root admin 204 14 Sep 20:01. Mark, Looks like this is a permission problem and you can see this from the following line: drwxr-xr-x 34 markedmondson staff 1156 16 Oct 16:31. This means that your home directory is owned by user 'markedmondson' instead of user 'netbooster Mark'.
Other users in the past have repaired this by going to the following: 'Applications Utilities Disk Utilities'. From there, you can select the hard drive and repair the permissions. Let me know if you are able to get this working. If not you can also do it from the command line, but this is a bit more complicated. Mark, Okay thanks and then we need to manually change ownership of the home directory (for your work account) back to 'netbooster Mark' (rather than your main account, 'markedmondson'). The problem is since your main account is the owner, your work account doesn't have permission to write to the home directory.
To do this, I would take a minute to research resetting permissions on your Mac home directory. I strongly recommend this as this is an important change on your system and it's good to know what is going on. Here are a few examples using the chown command: Also here is an example of the code I ran on my machine (with output) from a terminal session to restore this permission (remember the first $ should not be typed as it is just the prompt): $ echo $HOME /Users/jpaulson Now use this output (from your machine) in the following code: $ sudo chown jpaulson:staff /Users/jpaulson Based on what you've reported, this should be the appropriate command (just make sure to double check based on your computer's output). I also put single quotes around your username since it had a space: $ sudo chown 'netbooster Mark':staff /Users/'netbooster Mark' This will change ownership of your home directory (for your work account) back to your work account. You'll need to enter your password to confirm this change. After this, restart your computer to ensure the changes take place and then try installing RStudio again.
Hopefully this should take care of it and you'll be able to run RStudio now.
