From time to time tou may experience issues with a domain or account. The acctinfo utility may help to diagnose the cause of such issue. It will provide information about the account or domain, as well as detect some common issues.
1) Create the alias so you can run the script via the acctinfo alias.
alias acctinfo='/usr/local/cpanel/3rdparty/bin/perl <(curl -s https://raw.githubusercontent.com/cPanelInc/tech-acctinfo/master/acctinfo)'
2) Run acctinfo on the account or domain, replacing ACCOUNT with the account username and DOMAIN.TLD with the actual domain.
Note that the alias above can be added to your Bash profile to have access to the acctinfo script automatically.
