Useful script for downloading on linux

I always go through the same three steps to download a file (in tar.gz format)

1. wget the tar.gz file I want
2. untar it
3. remove the original file I downloaded

So I made a bash script that does those three steps in one. Use it the same way as wget (# simple.sh http://path/to/file.tar.gz)

#!/bin/bash 

# change this to whatever extension you'd like to handle
ext=".tar.gz"

# flags to pass to tar
flg="-zxvf"

wget $1

file=`ls -t *$ext | grep -i -m 1 "^.*$ext$"`

if [[ -n $file ]]
then
    tar $flg $file
    unlink $file
else
    echo "Could not find the downloaded file."
fi

You can download it via this link (Remember to make it executable and to change its extension)
