sam-cli — deploy

sam-cli.sh is a pure POSIX sh (busybox-compatible) wrapper around luna-send for the webOS SAM daemon. It runs on the target board (no bash there — only busybox ash), and can also drive the board remotely via --host/$SAM_HOST.

Target

Board: root@172.26.123.126 (LG webOS TV, aarch64)
Destination: /home/root/sam-cli
scp does not work (the TV has no sftp-server) — use the base64 pipe below.

Deploy

# from this directory
base64 -w0 sam-cli.sh | ssh -o BatchMode=yes root@172.26.123.126 \
  'base64 -d > /home/root/sam-cli && chmod +x /home/root/sam-cli && md5sum /home/root/sam-cli'

# verify checksum matches the local file
md5sum sam-cli.sh

Do not use ssh -tt for the transfer — the pty echoes the piped input and corrupts the file. -tt is only for running commands afterwards.

Why `/home/root`?

/usr/local/bin does not exist on this build.
/usr overlay is 100% full (30.8M/30.8M) — nothing can be written there.
/home/root is persistent with ~197M free.

Post-deploy notes

/home/root is not in PATH (/usr/bin:/bin:/usr/sbin:/sbin). Call by full path, or export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/home/root.
The board has no jq — the script's --ids and JSON-merge fallbacks are built in; --pretty degrades to raw JSON.
luna-send replies can take several seconds — keep the default --timeout 30 or raise it.

Smoke test (read-only)

ssh -tt root@172.26.123.126 "/home/root/sam-cli running --ids"
ssh -tt root@172.26.123.126 "/home/root/sam-cli list --ids | wc -l"
