Explore specific entries of a dump:

# Notes
|
||||
- Some commands require root permissions.
|
||||
If `sysdump.sh` is not run as root, these commands will not be executed.
|
||||
- List available entries:
|
||||
> cat dump.json |grep -o ".*:"
|
||||
- List available command versions:
|
||||
> cat dump.json |grep -o "cmd_.*_version"
|
||||
- For more infos on what is actually dump see `sysdump.sh`
|
||||
If `sysdump.sh` is not run as root, these commands will not be executed and the entries
|
||||
will not be reported in the dump file.
