Those scripts were executed by the operating system, and the results were served back by the web server. Many modern web servers can directly execute on-line scripting languages such as ASP, JSP, Perl, PHP and Ruby either by the web server itself or via extension modules (e.g. mod_perl or mod_php) to the webserver.
pkg-config is software development tool that queries information about libraries from a local, file-based database for the purpose of building a codebase that depends on them. .

In these languages, including the line __DATA__ (Perl) or __END__ (Ruby, old Perl) marks the end of the code segment and the start of the data segment.

In Linux, if the script was executed by a regular user, the shell would attempt to execute the command rm -rf / as a regular user, and the command would fail. However, if the script was executed by the root user, then the command would likely succeed and the filesystem would be erased. It is recommended to use sudo on a per-command basis instead.
