Java: Remove brackets / leading slashes from String

My Android-app have always presented the DNS-Server(s) with brackets / leading slashes like:

How can we get rid of these unnecessary characters ?

String myIp2Dns1:

String myIp2Dns1 = String.valueOf (LinkProp.getDnsServers()) ;

Log:

Log.d("myDnsInfo - Domain - ", "Domain = " + LinkProp.getDomains());
D/myDnsInfo: dns = [/10.0.2.3]

Solution:
Manipulation of String myIp2Dns1:

myIp2Dns1 = myIp2Dns1.replaceAll("[\\[\\](){}\"^/+\"]","");

This command removes brackets / slashes / backslashes from the String.

The output looks much better now:

daily compression of InfluxDB

InfluxDB is an open source time series database built by InfluxData and used in e.g. Openhab for data persistance.
For small computers like raspi’s it is a best practice to compress the database regurlarly.

Why not using cron ?

Well, it works.. the only (security)-drawback is to grant /bin/bash to the influx-user:

cat /etc/cron.daily/00influx:

#!/bin/bash
#execute
/home/pi/1_influxrepair.sh


cat /home/pi/1_influxrepair.sh:

#!/bin/bash
service influxdb stop
echo "before su"
su influxdb -c /home/pi/1_subscript.sh
echo "after su"
whoami
service influxdb start

cat /home/pi/1_subscript.sh:

#!/bin/bash
echo "now in sub shell"
whoami
cd /var/lib/influxdb
influx_inspect buildtsi -compact-series-file -datadir ./data -waldir ./wal
exit
echo "exiting sub shell"

cat /etc/passwd|grep infl:

modify influxdb:/bin/bash

done!
