In Linux, using Bash, I have two scripts:

1. script.sh is the main script, and
2. script_config.sh is the configuration for script.sh.

In script.sh, I do source script_config.sh to load all the config from there.

In script_config.sh, I do things like:

TEMPDIR=/mnt/sda1/temp 

I don’t know if this is the best way, but for me it’s okay, I have the config in a separate file and can load it into the main script.

In an old version of script.sh, I used shuf to read a file (cipher_to_use.txt) to get random input for which cipher to use with cryptsetup.

In cipher_to_use.txt, there are only 6 different ciphers listed, but some lines appear up to 10 times, so shuf chooses them more often but still randomly. That works okay for me.

But now, with script_config.sh, I’m looking for a way to continue this approach,
but I don’t want to write the 6 ciphers more than once in script_config.sh.

How can I use different ciphers with shuf, but make some appear more often than others, while listing each cipher only once in script_config.sh?

:edit

thanks nbanana for your ideas, but is there a way to make it a little bit different from your way?

if i write in script_config.sh this:

(chk = cipher has key)

chk1_name_="--cipher aes-cbc-essiv:sha256 --hash sha512 --key-size 256" chk1_weigt="15" chk2_name_="--cipher serpent-cbc-essiv:sha256 --hash sha512 --key-size 256" chk2_weigt="1" chk3_name_="--cipher twofish-cbc-essiv:sha256 --hash sha512 --key-size 256" chk3_weigt="1" chk4_name_="--cipher aes-xts-plain64 --hash sha512 --key-size 512" chk4_weigt="4" chk5_name_="--cipher serpent-xts-plain64 --hash sha512 --key-size 512" chk5_weigt="1" chk6_name_="--cipher twofish-xts-plain64 --hash sha512 --key-size 512" chk6_weigt="1" 

what have i to add in script.sh to become a ciphers_has_key_list-file

whit 15times in chk1, 1 chk2, and so on... ?

what if, if chk6 does not exist anymore?

what if, if there a chk7 and a chk8 ?

In Linux in bash i have two scripts.

script.sh is the main script and

script_config.sh is the configuration for script.sh.

In script.sh i do source script_config.sh to have all the config in there.

In script_config.sh i do things like

TEMPDIR=/mnt/sda1/temp

Dont know if this a good way, but for me is it oke, i have the config in an extra file can load it into the main script.

In a old version of script.sh i use shuf to read a file (cipher_to_use.txt) to become random input what chipper is to use with crytpsetup.

In cipher_to_use.txt are only 6 different ciphers write down, but some lines are up to 10times in theree becouse shuf use them more but chose it everytime randomly, thats works oke for me.

But now, with scipt_config.sh i am looking for a way to continue this but i will not write the 6 ciphers from cipher_to_use.txt more than onetime in to the script_config.sh file

How can i use different ciphers with shuf, but some more than orthers in script_config.sh?
