I usually work my batches in Excel or TextPad, and then copy/paste it into ArcGIS batch UI.
Is it possible to do the same in QGIS? The tutorials I've seen show how to fill the interface line by line, only. I'm using QGIS 2.10.1.
BTW, right now I'm trying to merge all seven bands of Landsat imagery into one multiband image file. I have 152 scenes with 7 bands each.
