Auto Answer Commands
I'm trying to script out the following commands;

newfs
ufsdump
ufsrestore

All of these commands ask me to continue.


ufsrestore asks
Code:
set owner/mode for '.'? [yn] y
Directories already exist, set modes anyway? [yn] y


newfs asks
Code:
newfs: construct a new file system /dev/rdsk/c1t1d0s0: (y/n)? y


I've skimmed over the man files, and I do not see a silent option.

I'm hoping there is something simple that I am missing.

Thanks in advance!

If you want to give yes,you change 'y' in the following script.If you want to give no,then you change 'n' in the following script.I tested the script with
rm -i option which will ask user confirmation before removing the file.

Code:
echo "y" | newfs
echo "y" | ufsdump
echo "y" | ufrestore

NOTE:You try this.Because,in my environment,the above commands aren't working.But,I tested this rm command with -i option.

Hi.

Have a look at the yes command.

Or if it's not that simple, you can put your responses in a file, like:

Code:
$ cat Test
read a
read b
read c

echo a is $a
echo b is $b
echo c is $c

$ cat response
y
n
y

$ cat response | ./Test
a is y
b is n
c is y

newfs worked
The echo "y" | newfs worked.

However,

Code:
echo "y" | ufsdump of - / |(cd /mnt; ufsrestore xvf -)

Did not. Is this possibly due to the extra pipe at the end for |(cd /mnt; ufsrestore xvf -) ?

Just for the heck of it, I also tried
Code:
echo "y" | (ufsdump of - / |(cd /mnt; ufsrestore xvf -))

with full failure.

Thanks.

I'm not to sure if I have the syntax right, but both of the following failed
Code:
yes y | ufsdump of - / |(cd /mnt; ufsrestore xvf -)
yes "y" | ufsdump of - / |(cd /mnt; ufsrestore xvf -)

As far as the script that you have mentioned, I'm not to sure how I can incorporate the answers with the commands that I am using.
Code:
set owner/mode for '.'? [yn] y
Directories already exist, set modes anyway? [yn] y

Where would I insert the $a? I can't echo it. I can't place it on a separate line or it one initiate until the first command is over. ufsdump/ufsrestore

I tried:
Code:
ufsdump of - / |(cd /mnt; echo "y" | ufsrestore xvf -)

but it doesn't work due to a "Broken Pipe"

Anymore suggestions?

Slightly off topic.

ufsdump of
Are you sure about the "o" switch? Maybe it should be a zero.

Btw. If you are trying to clone a root partition there are warnings in the Solaris 10 ufsdump manual about dumping an active mounted filesystem.

The command works.

I just need a way to answer the questions presented by the ufsdump/ufsrestore line.

I'm aware of the risks. But this isn't my problem at hand.

Firstly, sorry that I didn't reply sooner... but no! I've tried all manner of pipes, redirections and playing with file descriptors, but to no avail.

I even found some perl (from the OpenSolaris website) that proclaimed to address the "issue", but that didn't work.

What happens if you run it from cron? That's not connected to a terminal. Would it just give up or continue.

Still thinking Smilie
