# set up environment variables
TEST_DRIVER=/core/ffx-laboratory:test-driver::
LOCAL_RESOURCE_DIR=src/developer/ffx/plugins/component/copy/test-driver/resources
TMP_DIR=/tmp

# standard copy from host to target device 
ffx component copy $LOCAL_RESOURCE_DIR/file.txt $TEST_DRIVER/tmp/file.txt

# copy from host to target device with new file name
ffx component copy $LOCAL_RESOURCE_DIR/file.txt $TEST_DRIVER/tmp/new.txt

# copy from host to target device inferring the destination file name
ffx component copy $LOCAL_RESOURCE_DIR/file.txt $TEST_DRIVER/tmp/

# standard copy from target to host device 
ffx component copy $TEST_DRIVER/pkg/resources/foo.txt $TMP_DIR/foo.txt

# copy from host to target device with new file name
ffx component copy $TEST_DRIVER/pkg/resources/foo.txt $TMP_DIR/bar.txt

# copy from host to target device inferring the destination file name
ffx component copy $TEST_DRIVER/pkg/resources/foo.txt $TMP_DIR/
