System dump script

Dump various system informations into base64 encoded values and print them as json.

Usage

Run a dump:

./sysdump.sh > dump.json

Run a dump on a remote machine using ssh:

cat sysdump.sh | ssh user@host /bin/bash > dump.json

Extra ouput from ssh (e.g: MOTD) will be automatically cleaned by sysdump.sh.

To explore a dump (require jq), see help as follow:

./sysdump.sh -h
