Hi Isobel,

In the line:

[neuros-iMac-2:/] neuro% /etc/rc.common

You forgot the 'more'. The 'Permission denied' message was printed because you were trying to run the file 'rc.common' as a program.

In general, that tutorial should be fine to follow on OSX - you just might run into a few issues, such as this one, where files which do exist on Unix/Linux do not exist (or are named differently) on OSX.

Cheers,

Paul

Dear Paul,

This is the response I got from the terminal:

[neuros-iMac-2:/] neuro% /etc/rc.common

/etc/rc.common: Permission denied.

[neuros-iMac-2:/] neuro% 

What does this mean? Thanks a bunch. And do you know where I might be bale to get tutorial that will be based on the OS X system instead? Thank you so much!

Hi Isobel,

It looks like the tutorial which you are following was written for a Linux system. Even though OSX is also a Unix based system, it does not have an identical file system structure to Linux and, in this case, there is no file called '/etc/rc' on OSX.

You should be able to continue the tutorial by replacing '/etc/rc' with '/etc/rc.common' (or any other plain text file you happen to have around).

Cheers,

Paul

Dear all,

Following the instructions on the Basic Unix Tutorial page given as prior reading before attending the course: http://fsl.fmrib.ox.ac.uk/fslcourse/unix_intro/files.html

When I type in 'more /etc/rc' , this is the response I get:

[neuros-iMac-2:/] neuro% more /etc/rc

/etc/rc: No such file or directory

[neuros-iMac-2:/] neuro% ls

Applications Users dev net tmp

Library Volumes etc opt usr

Network bin home private var

System cores mach_kernel sbin

[neuros-iMac-2:/] neuro% head -15 /etc/rc

head: /etc/rc: No such file or directory

[neuros-iMac-2:/] neuro% head -15 /etc/rc

head: /etc/rc: No such file or directory

[neuros-iMac-2:/] neuro% 

I do not understand. 'etc' is a directory listed under the home user directory, but is not seen as a directory when i type in the command 'more /etc/rc'. Could somebody help me with this? Tqvm!!
