shell Piping

This sample app demonstrates using a shell script and some common utilities within a sandboxed app. The script echos some messages out to the stdout and then calls 'ls' piping the result to 'grep'. The output of the script can be read from syslog by using 'logread'.

start: manual

bundles:
{
    file:
    {
        // Bundling the script into the sandbox with the permissions needed to run it.
        [rx] utilPipes    /
    }
}

requires:
{
    file:
    {
        // Adding sh (shell), ls, grep and echo utilities into the sandbox.
        /bin/sh     /usr/local/bin/
        /bin/ls     /usr/local/bin/
        /bin/grep   /usr/local/bin/
        /bin/echo   /usr/local/bin/
    }
}

processes:
{
    run:
    {
        // Run sh (shell) and pass it the script for it to run.
        (sh utilPipes)
    }
}
