uncompress.sh

#!/bin/bash

if [[ "$1" == *.tar.lz4 ]]; then
        lz4 -dc --no-sparse "$1" | tar xf -
        #lz4 -d "$1"
        #tarf=${1%.lz4}
        #tar xvf "$tarf"
        #rm "$tarf"
else
        echo "$1 is not an archive tar.lz4"
        exit 1

exit 0

with GNU tar, use option -I lz4 would be better.
