###### Description: taskFword.sh is in the same directory as you. Maybe it will help you.

After I found that `.` `?` and `a` were the only three characters allowed and that `a` prints the environment variables, I ran the following command to execute taskFword.sh that the description says is in the same directory:-

```bash
. ????????????
```

Running this command seemed to do nothing helpful but running `a` after this gave us the flag as an environment variable:

**FwordCTF{BasH_1S_R3aLLy_4w3s0m3_K4hLaFTW}**
