usergen is a basic tool that takes a list of names and generates usernames with common username/email formats.
# only usernames, no emails
usergen -n names.txt
# usernames and emails
usergen -n names.txt -d target.com --save usernames.txt
# write generated usernames and emails to stdout
usergen -n names.txt -d target.comNOTE: must have GOPATH environment variable in your PATH and obviously go installed
go install -v github.com/bin3xish477/usergen@latest
