tend

tend is a command-line process manager for commands you run often. Save a command as a job, run one job or a group of jobs, and let tend restart them when they exit or when output hooks match.

It is useful for local development services, port forwards, and other long-running commands you want to start and supervise together.

Quick Start

Press Ctrl+C to stop running jobs.

Jobs are stored in ~/.tend/jobs as JSON files.

Examples

Run jobs by group:

tend create --group dev postgres kubectl port-forward svc/postgres 5432:5432
tend run --group dev

Run a shell command:

# Linux
tend create time sh -- -c 'echo "Time: $(date)"'

# Windows
tend create time cmd -- /C "echo Time: %TIME%"

Restart only after failures:

tend create --restart on-failure api cargo run

Use the port-forward template:

tend create --template port-forward postgres kubectl port-forward svc/postgres 5432:5432

See EXAMPLES.md for hooks that restart or stop jobs based on command output.
