.TP
.B \-\-install-completion
Install shell completion for the current shell.
.TP
.B \-\-show-completion

.TP
.B backup
Create a timestamped backup of the SSH config directory.
.TP
.B restore \fIPATH\fR
Restore SSH config from a backup.
.TP
.B cleanup [\-n]
Remove stale SSH control master sockets. Use \-n for dry-run.
.TP
.B log [\-n \fICOUNT\fR] [\-f]
Show recent sshctl activity log. Use \-f to follow (tail mode).
.TP
.B check [\-p \fIPATTERN\fR] [\-t \fISECS\fR] [\-c \fIMAX\fR]
Check connectivity to all hosts in parallel.
.TP
.B exec \fICOMMAND\fR [\-p \fIPATTERN\fR] [\-t \fISECS\fR]
Run a command in parallel across hosts.
.TP
.B csv [\-o \fIFILE\fR]
Export host inventory to CSV.
.TP
.B ansible [\-o \fIFILE\fR] [\-\-group-by \fIFIELD\fR]
Generate Ansible inventory from SSH config.
.TP
.B chmod [\-\-fix]
Check (and optionally fix) SSH directory permissions.
.SS Config Management
.TP
.B config show
Show all global Host * options.
.TP
.B config set \fIKEY\fR \fIVALUE\fR
Set an option in the Host * block.
.TP
.B config unset \fIKEY\fR
Remove an option from the Host * block.
.SS Host Management
.TP
.B host list
List all host aliases with HostName and ProxyJump.
.TP
.B host show \fIALIAS\fR
Show options for a specific host.
.TP
.B host add \fIALIAS\fR \fIHOSTNAME\fR [\-u \fIUSER\fR] [\-p \fIPORT\fR] [\-j \fIJUMP\fR]
Add a new host alias.
.TP
.B host edit \fIALIAS\fR \-\-option \fIOPT\fR \-\-value \fIVAL\fR

.TP
.B host remove \fIALIAS\fR [\-f]
Remove a host from its config file (with confirmation).
.SS ProxyJump
.TP
.B jump on
Restore all saved ProxyJump directives.
.TP
.B jump off
Save and remove all ProxyJump lines from conf.d files.
.TP
.B jump status
List all hosts with ProxyJump and show saved state.
.TP
.B jump auto [\-\-subnet] [\-\-no-subnet]
Auto-detect network environment:
- Probes jump gateways via TCP (respects HostName/Port from SSH config)
- Falls back to SSID matching against known internal networks
- Enables or disables ProxyJump accordingly.
.TP
.B jump networks [list|add|remove] [\-\-ssid \fIPATTERN\fR]
Manage internal SSID patterns for auto-detection (defaults: MobinNet*, Mobin*).
.SS Setup
.TP
.B setup completions [\-\-shell \fIbash|zsh|fish\fR]
Install shell completions.
.TP
.B setup agent [start|stop|restart|status]
Manage the ssh-agent systemd user service.
.TP
.B setup timer [cleanup|check] [\-a enable|disable|status]
Manage systemd timers.
.TP
.B setup git
Initialize git tracking in ~/.ssh.
.TP
.B setup init
Full setup: git + agent + timers + completions.
.SS Diagnostics
.TP
.B heal [\-\-dry-run]
Detect and fix config issues (typos, invalid options).
