Dear Dr Stephen,

Yes I am going back to the section in the basic unix tutorial on emacs. I will try first what you have advised me and post more questions later. Thanks!

Hi - that's almost right, except:

- in the case of most editors (eg emacs), starting the editor with a new filename such as
emacs my_new_script
will create that file for you (in this case the script file my_new_script).  So you don't need to "create" the file before opening the editor.

- then once you have created the file and exited the editor, you can then try running the script in the terminal.

I think at this  point you would probably benefit from going back to the basic unix tutorial
http://fsl.fmrib.ox.ac.uk/fslcourse/unix_intro/
and going through it in fine detail.

Cheers, Steve.

Dear Dr Stephen,

Does this mean that I have to create a file with the name that I want first, and then open it in emacs to edit it, before going back to the file in terminal again? Thanks!

Hi - no, that's not what that page is telling you to do.  You should be:

- create and edit a new script, for example with name "filename", for example by:
emacs filename

- then in this file put commands such as the 3 lines after the "- Example" paragraph heading, and then save the file and exit the editor (eg emacs).

- then run the chmod command to make the script file "filename" executable

- then to run it, do something like, in the terminal,     ./filename

Cheers.

Dear Dr Stephen,

tq for your advice. Yes I am. However i did not execute all the commands as I am afraid I might do something I will not be able to reverse in the system. Right now I am going through this:


When I type:

sh-3.2$ #!/bin/sh
sh-3.2$ chmod a+x filename
chmod: filename: No such file or directory

What does this mean? Thanks!

HI Dr Stephen,

So for all the exercises in the unix tutorial I should switch to either only "bash" or "sh"? is that why some commands are not working? By the way the system I'm using is OS X version 10.8.5 on the Mac. Tqvm!

Correct.  I would use "bash" if possible.

Btw - I assume that you're going through the basic unix tutorial

first?
Cheers.

Hi - I'm guessing that you are not using the most common "shell", which I would recommend to be "bash" or "sh".

It looks like you are currently using csh or tcsh, which is less common, and at this stage I would recommend switching to bash.   I'm not sure whether you're on Mac or linux, so I'm not quite sure how you can easily change this... do you have a local system administrator who can change this for you?

Cheers.

Dear Isobel,

.DS_Store is short for "Desktop Services Store" in Mac OS. If you want to delete them, just open "Terminal" (in the Applications/Utilities), and then type in
"sudo find / -name “.DS_Store” -depth -exec rm {} \;", next input your administrator password, finally all similar kinds of files effaced. Have fun!

Best,
Kai

Dear all,

I was going onto the basic unix tutorial and was playing around with emcas. Before doing that I created a directory named 'Belle" so that i could play around with emacs. However when I tried removing the directory this i the response I had:

[neuros-iMac-2:~] neuro% cd Belle
[neuros-iMac-2:~/Belle] neuro% ls
[neuros-iMac-2:~/Belle] neuro% emacs
[neuros-iMac-2:~/Belle] neuro% cd ..
[neuros-iMac-2:~] neuro% rmdir Belle
[neuros-iMac-2:~] neuro% mkdir Belle
[neuros-iMac-2:~] neuro% cd Belle
[neuros-iMac-2:~/Belle] neuro% emacs Belle
[neuros-iMac-2:~/Belle] neuro% emacs Belle
[neuros-iMac-2:~/Belle] neuro% rmdir Belle
rmdir: Belle: No such file or directory
[neuros-iMac-2:~/Belle] neuro% cd ..
[neuros-iMac-2:~] neuro% rmdir Belle
rmdir: Belle: Directory not empty
[neuros-iMac-2:~] neuro% cd Belle
[neuros-iMac-2:~/Belle] neuro% ls
#Belle# #ITF#
[neuros-iMac-2:~/Belle] neuro% rmdir ITF
rmdir: ITF: No such file or directory
[neuros-iMac-2:~/Belle] neuro% cd ..
[neuros-iMac-2:~] neuro% rmdir Belle
rmdir: Belle: Directory not empty
[neuros-iMac-2:~] neuro% rmdir Belle
rmdir: Belle: Directory not empty
[neuros-iMac-2:~] neuro% rmdir Belle
rmdir: Belle: Directory not empty
[neuros-iMac-2:~] neuro% cd Belle
[neuros-iMac-2:~/Belle] neuro% ls
#Belle# #ITF#
[neuros-iMac-2:~/Belle] neuro% ls -la
total 8
-rw-r--r--   1 neuro  staff     0 Jul 18 16:37 #Belle#
-rw-r--r--   1 neuro  staff    28 Jul 18 16:43 #ITF#
drwxr-xr-x   4 neuro  staff   136 Jul 18 16:52 .
drwxrw-r--+ 56 neuro  staff  1904 Jul 18 16:02 ..
[neuros-iMac-2:~/Belle] neuro% rmdir #ITF#
rmdir: #ITF#: Not a directory
[neuros-iMac-2:~/Belle] neuro% 

There is a hidden file in it as well name '.DS_Store"

Can somebody let me know what I have done and how do I rectify it? Also, how will I be able to remove the directory 'Belle' completely? Thanks!!
