I suggest writing a script that looks at the output of the 'file'
command and picks the program based on that.

Something like:

f="`file \"$1\"`"
echo "$f" | grep -q '7z archive data' && p7zip -d "$1" && exit
echo "$f" | grep -q 'Zip archive data' && unzip "$1" && exit
echo "No program known to decompress: $f"

Personally I hardly ever see 7z format archives, and never any
pretending to ZIP. Or if I did, then I probably just assumed they'd
been corrupted.
