In this challenge, you will log in with the username and password `pentesterlab`. The goal is to find a key stored in an environment variable defined using the `export` command in a `.bashrc` file. When users start a bash shell, the `.bashrc` file is loaded, and it can be used to define aliases and set environment variables, which may contain sensitive information like credentials or API secrets.

Given that the system has numerous users, manually checking each `.bashrc` file would be laborious. Instead, you will use the `find` command to locate all `.bashrc` files on the system. Then, you will use `grep` to search these files for the `export` command and further filter the results to find the specific environment variable `PTLAB_KEY`. This approach will efficiently pinpoint the required key and complete the challenge.
