Shell Programming and Scripting

No, not on this box, but sh is in there.
The test box has a nightly build on

0.7 Sardaukar (revision 3514)
built on Fri Jun 6 22:03:39 CEST 2008

Managed to create a small script just now, it creates a directory /root/.ssh and then copy the authorized_keys2 file to it, from local disk and change its permissions.
Can get it to run and work from the CLI, just trying to get it to work from PostInit in the WebGUI now.

The script in your eyes is probably the equivalent of a 3 year old child's scrawl with crayon, but at least I managed to get it to work.

No, it is not there.

I have nightly build
0.7 Sardaukar (revision 3514)
built on Fri Jun 6 22:03:39 CEST 2008
on this test box

I can always put a 0.69b4 back on.

Anyway. I have had some success.
I managed to create a small script that creates a directory, copies my authorized_keys2 file to it from a local HDD, and chmod's it.
the script, also stored on the local HDD I have got it running PostInit.
It also seems to work. Probably very childish script that you guys could have done in a much more elegant way, but it works, I have acheived something today any how.

Thanks for your help Dan, would not have done it without you.


So thanks Dan,

Neil


Edit: Sorry for the long list of posts, don't quite know what is happening, they were not there when I started this post, then after posting, they were suddenly there. Maybe the browser is pulling the page form cache rather than refreshing? I am running all from USB stick and portable apps. Any way that is not important.

I would still like to get a basic sh shell, so I can get on with the tutorial

0.7 is in alpha stage for the moment. Once FreeBSD 6.4 will be released we can release the 0.69 final and move on with 0.7.

PS: Take a look at https://www.unix.com/shell-programmin...-spaces-2.html

Gulp.....wont be trying anything like that lot for a while......ever....


I was happy to get this to work and then work out the syntax to put in the PostInit line toget it to run without being in that directory

cd /root
mkdir .ssh
cp /mnt/BootDisk/authorized_keys2 /root/.ssh/
cd /root/.ssh
chmod 600 authorized_keys2

OK, so what would be a neater way of doing the above?

You don't need to cd to a directory -- any file-oriented command will accept a full path name just as well as a plain file name.

Code:

mkdir -p /root/.ssh  # -p makes it not do anything if the directory exists already
cp /mnt/BootDisk/authorized_keys2 /root/.ssh/
chmod 600 /root/.ssh/authorized_keys2

If you want to avoid repeating the path name, use a variable to abbreviate it.

Code:

p=/root/.ssh
a=authorized_keys2
mkdir -p "$p"
cp /mnt/BootDisk/"$a" "$p"/
chmod 600 "$p"/"$a"

This way, it's also easier to globally replace the path name if you ever want to do that -- only one place to change.

PS. Since this question is by and large unrelated to your original question,. perhaps you should have started a new thread.

Yes, your right, prob should have startd a new thread.

I see what you mean when you said:

You don't need to cd to a directory -- any file-oriented command will accept a full path name just as well as a plain file name.

At first I was wondering; "If you do not use cd to move into a dir, how did you move into that directory."

If I understand correctly I think what you are saying is that,you don't need to go into that directory to create a new directory inside it, just use the complete path.

I had just started to read a bit about variables, and seen basic use in the tutorial I have been trying to work through....but until I get sh rather than csh, I am still a bit stuck.

Later today, I will downgrade my test box to the older 0.69b4 as suggested by Dan, and I should be able to learn a bit more.

Up until two weeks ago, I had not even looked at doing anything via the command line since I was at school 20 years ago, so learning a lot at the moment.

Thanks for the help
