    Petals CLI can process command using several ways:

    • one command defined as argument on the command line,
    • several commands entered using the mode 'console',
    • several commands entered using the stdin that can be redirected (using the option '-s')

    Petals CLI can't process a file of commands directly.

    It should be more usable to have:

    • an option to execute the command on command line, as the system tool 'su': petals-cli.sh -c <command>
    • by default, the mode 'console' is displayed: petals-cli.sh
    • the file of commands to execute is set as argument on command line: petals-cli.sh <my-command-file>
    • to use the stdin as stream of commands, use the 'special' filename '-', that is the standard way (see the system tool 'tar'): petals-cli.sh - < my-file

    So the stding redirection will be clearer (see PETALSESBCLI-9)

To prevent to mix the mode 'console' with a stdin redirection, it is better to have:

  • by default, a file is expected to be executed,
  • a new option '-C' enables the mode 'console'
  • the mode 'console' is provided by a new script 'petals-console.sh' that invokes 'petals-cli.sh -C''. On linux it should be more standard to use a symlink, but I'm not sure that is possible to keep it in the final zip file.

As it is not more usable than the option '-C' on command line, the wrapper script is removed
