Im trying and testing some script that will install proper version of daemon, but first in the code i want check if its running for real and check the version of the daemon(Then will force download and update it). But im stucked at the beginning.

#!/bin/bash



RED='33[0;91m'

GREEN='33[1;32m'

YELLOW='33[1;33m'

NC='33[0m'`



#Checking Server status

/usr/local/bin/evos-cli getinfo

if [[ "/usr/local/bin/evos-cli getinfo" = "error: couldn't connect to server" ]];

then

    echo -e "${GREEN}I will start Evos server then i check for version... ${NC}"

    evosd

    sleep 10s 

else

    echo -e "${GREEN} Server is running i check for the version soon! ${NC}"

    sleep 2s

fi



#Version Checking

/usr/local/bin/evos-cli --version

if [[ "/usr/local/bin/evos-cli --version" = "Evos Core RPC client version v1.1.3.0-2ba4298" ]];

then

    echo -e "${GREEN} Version of wallet is correct! ${NC}"

else

    echo -e "${YELLOW} Version of wallet is Incorrect! ${NC}"

fi



#Checked Status

sleep 3s

echo -e "${YELLOW} Status Checked! ${NC}"

There are many commands available on daemon, if server is stopped and you type any command you will receive "error: couldn't connect to server" Thats why i want to trigger else option if "error: couldn't connect to server" not happen . Even the server is stopped its triggering else command which skip the starting server process and say Server is running. The version checker is also triggering else option even the version match with the command provided. The version was triggering to correct version when i used this code (But code is useless because anything there will say correct)

/usr/local/bin/evos-cli --version

if [ "/usr/local/bin/evos-cli --version Evos Core RPC client version v1.1.3.0-2ba4298" ]; 

then

    echo -e "${GREEN} Version of wallet is correct! ${NC}"

else

    echo -e "${YELLOW} Version of wallet is Incorrect! ${NC}"

fi



#Checked Status

sleep 3s

echo -e "${YELLOW} Status Checked! ${NC}"

evos-cli getinfo , or /usr/local/bin/evos-cli getinfo example of how command can be triggered in the terminal.

Tried many variants but i cannot figure out.

In the test

if [[ "/usr/local/bin/evos-cli getinfo" = "error: couldn't connect to server" ]];

you seem to want to compare the output of /usr/local/bin/evos-cli getinfo to a string. What you probably want to do in this particular test is to test whether the command was successful or not.

This would be done with

if /usr/local/bin/evos-cli getinfo >/dev/null 2>&1; then

    # this worked

else

    # the command failed

fi

To compare the output of a command, use a command substitution:

if [ "$(/usr/local/bin/evos-cli --version)" = "Evos Core RPC client version v1.1.3.0-2ba4298" ]; then

    # version was the expected string

else

    # we got an unknown version

fi

or, if you just want to match the first part of that string, using bash,

if [[ "$(/usr/local/bin/evos-cli --version)" == "Evos Core RPC client version v1.1.3.0"* ]]; then

    # version was the expected string

else

    # we got an unknown version

fi
