ypetya / .bashrc

Created September 29, 2013 13:11

Created this 'ln' function into my .bashrc, it emulates a 'cp' call instead of the real 'ln -s' which is not supported on windows MinGw.


	function ln() {
	echo "WARNING! 'ln' is an unsupported command on this platform."
	echo " * The following command was called:"
	echo "ln $@"

	if [ $1 = "-s" ] ; then
	echo " * Trying to translate it to a simple copy command : "
	COMMAND="cp -R $2 $3"
	echo "$COMMAND"
