Code:

### TO DO: Check if destination exists and is a directory, exit on error

for path in $(### TO DO: Get the list of mp3 files in the source directory)

You need to edit the supplied script and substitute suitable unix commands wherever the the lecturer has placed a comment line "### TO DO".

For the above command, after editing it might read something like:

Code:

for path in $(find "${source}" -follow -type f -name "*.mp3" -print)

The sample script is correctly structured. You don't need to change the order of the commands - just find the appropriate command each time the lecturer has given a sample line or asked you to insert a line which you have written from scratch.
Big Hint: Comment out the lecturer's incomplete sample lines until you can edit the script to produce valid syntax. This will enable you to build the script line-by-line with valid syntax and debug from the top down.
Another hint: Use echo or printf statements to check the value of variables while you are testing the script.

Quote:

# The script usage will be as follows:
# momo source_directory [destination directory]

In your sample code, the source and destination directories have been set to hard values rather than from parameters supplied when the script was invoked ($1 and optionally $2). This is not correct. There is a lot of useful information in the comments in the lecturer's script.

Good luck.

build-lives-rfx-plugin(1)				      General Commands Manual					 build-lives-rfx-plugin(1)

NAME

       build-lives-rfx-plugin - builds rendered effects for LiVES

SYNOPSIS

       build-lives-rfx-plugin script_name [plugin_dir] -get section file

DESCRIPTION

       This perl script is used by LiVES to compile an RFX (rendered effect) plugin for LiVES. It is generally called from build-lives-rfx-plugin-
       multi for a script which has a language code representing LiVES-perl. The script_name must be  the  full  (absolute)  path  to  the  plugin
       script,	and  plugin_dir  can  be  used to specify the output directory where the compiled plugin should be generated. If plugin_dir is not
       defined then /tmp is assumed.

       The second variant with -get is used to print out a script section from a plugin script to stdout. It is generally only used internally	by
       LiVES.

       Return values The script returns the following values

       0 - success 1 - the value of a trigger was greater than the number of parameters 2 - a value could not be read from the script file 3 - the
       language code of the plugin script was not equivalent to LiVES-perl 4 - the API version level of the plugin script  was	invalid  5  -  the
       <define> section was missing from the plugin script
