+```
+

+```
+
+Filter sandboxes by metadata and print JSON:

+```
+

+
+```bash
+e2b sandbox info <sandboxID>
+```
+

+
+```bash
+e2b sandbox connect <sandboxID>
+```
+
+Stream sandbox logs until the sandbox closes:
+
+```bash
+e2b sandbox logs <sandboxID> --follow
+```
+
+Filter logs by level or logger prefix:
+
+```bash
+e2b sandbox logs <sandboxID> --follow --level warn
+e2b sandbox logs <sandboxID> --format json --loggers Envd,Kernel
+```
+
+View live resource metrics:

+e2b sandbox exec <sandboxID> -- python -V
+```
+
+Pass environment variables to a sandbox command:
+
+```bash

+```
+
+Pipe stdin into a sandbox command:

+```
+
+Use `--` before the remote command when you want to clearly separate CLI flags from the command being executed inside the sandbox.
