Command Launcher#

Application and Bashscript Launcher#

This plugin allows you to execute system commands and start bash scripts.

Usage#

Application launcher#

The application launcher allows you to call bash applications or commands with parameters from nymea. Once, the application started, the running state will change to `` true``, if the application is finished, the running state will change to `` false``.

Example

An example command could be espeak. (apt-get install espeak)

espeak -v en "Chuck Norris is using nymea"

Bash script launcher#

The bashscript launcher allows you to start a bash script (with parameters) from nymea. Once, the script is running, the running state will change to `` true``, if the application is finished, the running state will change to `` false``.

Example

An example for a very useful script could be a backup scrip like following backup.sh script.

#!/bin/sh
# Directories to backup...
backup_files="/home /etc /root /opt /var/www /var/lib/jenkins"
# Destination of the backup...
dest="/mnt/backup"
# Create archive filename...
day=$(date +%Y%m%d)
hostname="nymea.io"
archive_file="$day-$hostname.tgz"
# Print start status message...
echo "Backing up $backup_files to $dest/$archive_file"
date
echo
# Backup the files using tar.
tar czf $dest/$archive_file $backup_files
echo
echo "Backup finished"
date
echo "==========================="
echo "  DONE, have a nice day!   "
echo "==========================="

To make the script executable use following command:

chmod +x backup.sh
