mapinfo - Batch Script to merge tab fles in a directory

Very similar to this question Merging multiple .tab files? can someone please help me with a batch script for this?

Based on the answer in the above I have

#!/bin/bash
for i in *.tab;
do 
ogr2ogr -update -append merge.tab i  -f “MapInfo File” -nln merge 
done

but when I run it it fails with

FAILURE:
Unable to open datasource `i' with the following drivers.

and then lists the drivers

Answer

For completeness, and based on the above comments, this should work:

ogr2ogr -update -append merge.tab $i -f “MapInfo File” -nln merge
