To make it easier to read I’ve split this into separate lines to post. You could remove the ‘;\’ and it create a multi-line bash script.
When you download Landsat data it comes as a .tar.gz archive (or .tar.bz if you download from Google). To uncompress the files into a separate folder for each scene the following series of bash commands can be used:
for scene in `ls *tar.gz | sed 's/.tar.gz//'`;\ do echo "Uncompressing ${scene}";\ mkdir ${scene};\ mv ${scene}.tar.gz ${scene};\ cd ${scene};\ tar -xvf ${scene}.tar.gz;\ cd -;\ done
This will list all the files matching ‘*.tar.gz’, remove the extension (using sed), print the scene name (echo), make a directory (mkdir), move the .tar.gz archive into it (mv), untar (tar -xvf) and then change back to the original directory (cd -).
You can also use the ‘arcsiextractdata.py’ tool, as detailed in an earlier post
