[PLUG] Determining when a shell script is sourced

["K.S. Bhaskar" <ksbhaskar@gmail.com>]

We have a shell script (starts with #!/binsh and is at https://gitlab.com/YottaDB/DB/YDB/blob/master/sr_unix/ydbinstall.sh) that should preferably not be source'd. Is there a way to test within the script whether someone has source'd it and generate an error without terminating the shell session that source'd it? Thank you very much.

Regards
