Dear Alessandro,
you can use sed to replace the RANDOMIZ line in the input file with a new one. Take a look on the following partial bash script.
seed_string=`printf "% 8i" ${seed}`
sed -i "s/^RANDOMIZ.*/RANDOMIZ 1.0${seed_string}.0/" ${inputfile}
I hope this helps.
Kind regards,

Subject: [fluka-discuss]: change random seed
Dear FLUKA experts,
We are going to do some heavy simulations. To speed ut the calculation
time we thought to launch more simulations in series with a fewer number
of particles. To avoid having the same results we want to change the
seed of the random number generator. I want to ast to you if it is
possible to change it using the include comand or you think there is a
better solution? The complete idea is to use a bash file to change the
seed and then relaunch the fluka run. In this way, it will be possible
to do all of this using only one comand on the server.
Thank you in advance and best regards, Alessandro Calamida.
