Untar and gunzip all files in a directory

I needed a little script to expand a bunch of tarred and gzipped files in a directory and I needed a log of what happened.. and didn’t happen (errors). So, here it is.

#!/bin/bash
 # jcz 16-mar-12
 # filename: untgzall.sh
 # untars (with gzip) all tar gzips in the directory
 # where it is run. Logs all file contents
 # and errors to a text file in the directory
 # in which it is run
 #

Which gives us the following output at the command line
