In the docs I read: There are certain caveats about these scripts which you should take into account. Number one, each must fit inside a 8192 buffer, and number two, they should be non-interactive. Anything which requires manual input from the user is wrong, as this will break non-interactive RPM installation procedures. Regards, Miguel Beccari

I builded a RPM from scratch of an application of mine.
The SRC rpm works: it builds 2 i586 architecture packages, it has got
good controls, it check dependecies and so on.
My trouble is this: how to force the user to answer some questions
before install the package ?
I wrote down theese lines:
%pre
echo Bla bla bla.;
echo -n Answer (yes | no | later);
read chiave
while ( test -z $chiave ); do
read chiave
done;
that produce a /var/tmp/rpm-tmp.19101 as follow:
echo Bla bla bla.;
echo -n Answer (yes | no | later);
read chiave
while ( test -z $chiave ); do
read chiave
done;
The problem is that $chiave is NEVER != zero.
Some one can help me ?
Are you saying the script behave differently in the RPM than if you just
run it? I would do something a little more bulletproof, which would force
them to answer one of your choices, unless they ctrl-C out of it:
#!/bin/sh
echo Bla bla bla.;
GoodAnswer () {
# do something now
echo You answered $chiave
}
GetInput () {
echo -n Answer (yes | no | later);
read chiave
while [ -z $chiave ]; do
GetInput
done;
}
GetInput
case $chiave in
yes | no | later)
GoodAnswer
;;
*)
GetInput
;;
esac
Of course if they install with rpmdrake or whatever, you need to call up a
terminal window. Others may have even better suggestions.

Yes (I am saying the script behave differently).
I used your suggestions, but the result is the same.
If I run sh /var/tmp/rpm-tmp.54377 I have got the promt Answer (yes |
no | later)
If I answer the script goes on as well. It is OK.
But when I run rpm -Uhv I have a loop: Answer (yes | no | later) Answer
(yes | no | later) Answer (yes | no | later) Answer (yes | no | later)
Answer (yes | no | later) Answer (yes | no | later) [etc...]
This because of $chiave is empty
GetInput () {
echo -n Answer (yes | no | later);
read chiave
while [ -z $chiave ]; do
GetInput
done;
}
Because of $chiave is empry GetInput is looped.

It is so. In fact I used something like %pre $bashscript = /tmp/myfile echo #!/bin/sh $bashscript echo Stew Benedict suggestion $bashscript chmod 700 $bashscript sh $bashscript So i was REALLY sure it was a bash script to be executed (sorry but I am new to rpms) and the problem was the same. Then I run /tmp/myfile and it worked... so I think the input is redirected from /dev/null. OK. I will write a mini setup program as Microsft does ;) Up to now I just echo out the instructions and the license (with a line that sounds like 'using the software presumes you have accepted the license terms at all Regards, Miguel Beccari

I will write a mini setup program as Microsft does ;) Up to now I just echo out the instructions and the license (with a line that sounds like 'using the software presumes you have accepted the license terms at all Intel's free compiler, Mathematica, and maple take the following approach: write a simple script that reviews the license, asks/determines which parts /things to install, unpacks the appropriate rpm's and installs them -- relocating to users chosen path if that is an option. These can be run from a script by catting in the required answers: install_ace_package my_options. Generally such packages are add-ons and go in /opt and are individually installed. On the other hand if you have used rpm to mark your license type and have included it in the distro then arguable an installer is/should be aware of it. VMware + staroffice(?) take an alternative approach -- rpm's to install but a first-time script to be run by users to setup the network daemons etc: vmware-config.pl and soffice. Alternatively you can have the program auto-detect different features like SSE1/2 MMX support for multimedia libraries. Hopefully you should be inspired by one of these examples. Good luck, Q.
