Shell utilities

The module msp430.shell provides some useful scripts for the shell.

msp430.shell.command

This tool emulates a number of shell utilities. The idea is that makefiles or similar build tools can use these commands to be OS independent (so that the same set of commands works on Windows, GNU/Linux, etc.).

Command collection:

• cat Show file contents.
• cp Copy files.
• expand Expand shell patterns (“*.c”, “?” etc.).
• false Simply return exit code 1
• list This text.
• mkdir Create directories.
• mv Move/rename files.
• rm Delete files/directories.
• touch Update file date, create file.
• true Simply return exit code 0

More help with “command.py COMMAND –help”

Example:

python -m msp430.shell.command rm -f no_longer_needed.txt
python -m msp430.shell.command cp src.txt dst.txt

msp430.shell.watch

This tool watches one or multiple files for changes. When a change on one file is detected it runs a given command. This could be used e.g. to automatically trigger a download when a hex file has changed or trigger compilation when one of the source files has changed.

Usage: watch.py FILENAME [FILENAME...] –execute “some/program/ –”

Options:

-h, --help	show this help message and exit
-x COMMAND, --execute=COMMAND
	run this command when watched file(s) changed, – is replaced by FILENAME(s)
