Install and use the CLI

Install and use the CLI

Install an approved Debian package:

sudo apt install ./ohtools_0.3.2_amd64.deb

The binary is installed at /usr/bin/ohtools. Configuration and policy live under /etc/ohtools; plugins are installed under /usr/lib/ohtools/plugins.

Common commands

ohtools system info
ohtools system health
ohtools disk usage /
ohtools service status nginx.service
ohtools plugin catalog list
ohtools plugin outdated

Every primary command supports --json. JSON mode writes exactly one Result v1 document to stdout; diagnostics belong on stderr.

Mutations

ohtools never invokes sudo. A mutation that requires privilege returns exit code 3 with rerun guidance:

sudo ohtools service restart nginx.service --dry-run
sudo ohtools service restart nginx.service

Use --yes only to bypass confirmation. It cannot bypass policy, privilege, audit, planning, or verification.
