Changing daemon password Transmission 2.42

[Random]

Hello, I'm using ubuntu and running Transmission 2.42, I have a bash script that stops the transmission service, modifies the password in the settings.json file and the restarts the service, however the settings.json just reverts immediately back to the old password :/
Any ideas as to why and what I'm doing wrong?

Yeah, before the daemon is restarted it grabs and echos the settings.json file with the new password nicely where it should be, then it starts the daemon and re-echos the file with the old password back

#!/bin/bash


if [ $# -ne 1 ]; then
echo "usage: ${0##*/} <username>"
exit
fi
user="${1}"

sv -v down "/service/transmission-daemon.$user";

base_dir="/var/lib/transmission-daemon"

user_dir="${base_dir}.${user}"

user_conf="${user_dir}/info/settings.json"


read password
new_line=' "rpc-password": "'$password'",'
perl -pe "s/.*/$new_line/ if $. == 48" < $user_conf #outputs new file with new pass (dosen't seem to save though?)
newPass=`grep -i "rpc-password" "$user_conf"`
#echo $new_line
echo $newPass #echos same old pass
echo $new_line #echos new pass
echo "$(tput setaf 2)Pass for user $user changed to $password $(tput sgr0)"

sv -v up "/service/transmission-daemon.$user";
sv -v term "/service/transmission-daemon.$user";
sv -v hup "/service/transmission-daemon.$user";

newPass2=`grep -i "rpc-password" "$user_conf"` #echos same old pass once again
echo $newPass2

it doesn't look like your script ever writes the changes to the file, it just gives screen output. maybe try this instead..

Code: Select all

cat $user_conf # echo file before change

read password
sed -i -e "s/.*rpc-password.*/    \"rpc-password\": \"$password\",/" $user_conf

cat $user_conf # echo file after change

above uses bash's sed in-place substitution

Aha, that worked tyvm
