How to handle appcenter login error in shell script?

Question

I am using the below script for publishing the ipa to appcenter.

ipaPath=<PATH TO MY IPA FILE>
echo "Found ipa at $ipaPath"

if [[ -z ${ipaPath} ]]

then

    echo "No ipas were found, skip publishing to App Center"

else

    appcenter login 
    appcenter distribute release \
        --group Collaborators \
        --file "${ipaPath}" \
        --release-notes 'App submission' \
        --app <username_or_organization>/<application_identifier> \
        --quiet
fi

I need to exit if the login is failed and don't want to run the distribute command. how to check the login status and handle the error?

You could use command substitution to capture the result of appcenter login into a variable, then search the variable contents for a specific string (or lack of). For example:

reply="$(appcenter login --token ${token})"

if [[ $reply == *"Error"* ]]; then
  echo "A problem occurred! ${reply}"
else
  appcenter distribute release
  ...
fi
