wut

Web Update Tool — a server that dynamically generates and serves shell scripts to client shells over HTTP.

This tool is expected to be run locally and interactively.

Some operations cannot work over SSH because they install GUI tools.

Some operations create dynamic prompts for the user and cannot be scripted.

prerequisites

• wut-config — config repository cloned as a sibling directory (../wut-config)
• Deno or Docker — to run the server

server

Start the server (requires Deno):

deno task dev

Or via Docker:

deno task dev:docker

# Stop when done
deno task dev:docker:down

The server runs on port 9000 by default. Set PORT to override.

shell client

Set WUT_URL to your server address, then paste the corresponding wut function into your shell config.

nu

Nushell is supported on Unix and Windows for all commands.

$env.WUT_URL = 'http://my-server:9000'

def wut --wrapped [...args] {
  mut url = $"($env.WUT_URL)" | str trim --right --char '/'
  mut url = $"($url)/sh/nu"
  mut url = $"($url)/($args | str join '/')" | str trim --right --char '/'

  nu --no-config-file -c $"( http get --raw --redirect-mode follow $"($url)" )"
}

pwsh

Powershell is supported on Windows for script. All other commands invoke Nushell.

$env:WUT_URL = 'http://my-server:9000'

function wut {
  $url = "${env:WUT_URL}".TrimEnd('/')
  $url = "${url}/sh/pwsh"
  $url = "${url}/$($args -Join '/')".TrimEnd('/')

  pwsh -noprofile -c "$( Invoke-WebRequest -ErrorAction Stop -ProgressAction SilentlyContinue -Uri "${url}" )"
}

zsh

Zshell is supported on Unix for script. All other commands invoke Nushell.

export WUT_URL='http://my-server:9000'

function wut {
  local url=$(echo "${WUT_URL}" | sed 's:/*$::')
  local url=$(echo "${url}/sh/zsh")
  local url=$(echo "${url}/$(echo "$*" | sed 's/ /\//g')" | sed 's:/*$::')

  zsh --no-rcs -c "$( curl --fail-with-body --location --no-progress-meter --url "${url}" )"
}
