+## Sessions Command
+
+### Session Search
+
+When you have a number of sessions open, searching can be a useful tool to navigate them. This guide explains what capabilities are available for navigating open sessions with search.
+
+You can get a list of sessions matching a specific criteria within msfconsole:
+
+```msf
+msf6 payload(windows/meterpreter/reverse_http) > sessions --search "session_id:1 session_id:2"
+Active sessions
+===============
+
+  Id  Name  Type                     Information                                    Connection
+  --  ----  ----                     -----------                                    ----------
+  1         meterpreter x86/windows  WIN-ED9KFH65RDH\Zach Goldman @WIN-ED9KFH65RDH  192.168.2.1:4444 -> 192.168.2.132:52190 (192.168.2.132)                                         
+
+```
+
+Currently, the only supported keywords for search are `session_id`, `session_type`, and `last_checkin`. These keywords can be combined to further filter your results, and used with other flags. For example:
+
+```msf
+msf6 payload(windows/meterpreter/reverse_http) > sessions --search "session_id:1 session_type:meterpreter last_checkin:greater_than:10s last_checkin:less_than:10d5h2m30s" -v
+
+Active sessions
+===============
+
+  Session ID: 1
+        Name:
+        Type: meterpreter windows
+        Info: WIN-ED9KFH65RDH\Zach Goldman @ WIN-ED9KFH65RDH
+      Tunnel: 192.168.2.1:4444 -> 192.168.2.132:52190 (192.168.2.132)
+         Via: exploit/multi/handler
+   Encrypted: Yes (AES-256-CBC)
+        UUID: 958f7b976db67d60/x86=1/windows=1/2023-10-19T12:38:05Z
+     CheckIn: 21725s ago @ 2023-10-19 09:26:08 -0500
+  Registered: No
+
+```
+
+Of note in the above example, `last_checkin` requires an extra argument. The second argument must be either `greater_than` or `less_than`. The third argument can be a sequence of alternating amounts and units of time (d: days, h: hours, m: minutes, and s: seconds), i.e. `5m2s`, `10d`, or `1d5m`.
+
+### Killing stale sessions
+
+If `--search` is used in conjunction with `--kill-all`, it will restrict the latter function to only the search results. For example:
+
+```msf
+msf6 payload(windows/meterpreter/reverse_http) > sessions -K -S "session_type:meterpreter"
+[*] Killing matching sessions...
+
+Active sessions
+===============
+
+  Id  Name  Type                     Information                                     Connection
+  --  ----  ----                     -----------                                     ----------
+  1         meterpreter x86/windows  WIN-ED9KFH65RDH\Zach Goldman @ WIN-ED9KFH65RDH  192.168.2.1:4444 -> 192.168.2.132:52190 (192.168.2.132)
+  2         meterpreter x86/windows  WIN-ED9KFH65RDH\Zach Goldman @ WIN-ED9KFH65RDH  192.168.2.1:4444 -> 192.168.2.132:52192 (192.168.2.132)
+
+[*] 192.168.2.132 - Meterpreter session 1 closed.
+[*] 192.168.2.132 - Meterpreter session 2 closed.
