I have 7 bands of Landsat and I would like to combine all layers into one layer.
Can ArcMap 10 do this like Erdas software can?

As commented by the asker:
For anyone that's interested, I was able to get this to work by instead using a python script to first generate parameter files, and then a batch file as documented at http://www.hexagongeospatial.com/Libraries/Support_Documents/Howtobatchlayerstack.sflb.ashx. It isn't what I initially intended to do, but it accomplishes the automation I am looking for in processing 100's of landsat images! I have also been using this method to create parameter files/batch files for some of my .gmd models to automate these as well..it's been quite useful.
I know this an old question, but here is another way to unstack multiband-image. The solution is done using QGIS with Orfeo toolbox installed. You can use split image tool from Orfeo toolbox. The Split Image, as you can see below, will split the multiband-image that you have into separate images, and each image has one band.
You need to specify an output filename. The output filename will be used to get the prefix and the extension of the output images to write.
In the example above, I just put Image.tif. You can choose any name you prefer.
However, Orfeo toolbox is not downloaded by default into QGIS. You need to download it separately, or better use OSGeo4W advanced install to download Orfeo toolbox from there.
