### Check open Ports

You can do it by running `ss -tunlp` (or `netstat` on older systems)

```
tbfcapp@tbfc-devqa01:~$ ss -tulpn                                                                                                       
Netid         State          Recv-Q         Send-Q                      Local Address:Port                    Peer Address:Port         
Process                                                                                                                                 
udp           UNCONN         0              0                                 0.0.0.0:53                           0.0.0.0:*            
udp           UNCONN         0              0                      10.48.178.154%ens5:68                           0.0.0.0:*            
tcp           LISTEN         0              32                                0.0.0.0:21212                        0.0.0.0:*            
tcp           LISTEN         0              151                             127.0.0.1:3306                         0.0.0.0:*            
```

### Recursively search for files

```
dir C:\Windows\System32\*.txt /s /b
```

* `dir` → list files
* `C:\Windows\System32\*.txt` → match **all `.txt` files** in `System32`
* `/s` → **search recursively** through all subdirectories
* `/b` → **bare format** (full paths only, no headers or extra info)
