What would you like to do?
Minimal rpm2cpio using only bash, grep, tail and a decompressor
RPMHDRLGTH=$(LANG=X grep -abom1 '.7zXZ\|]'$'\000\000''....'$'\377\377\377\377\377\377''\|BZh9\|'$'\037\213\b' "$1")
case "$RPMHDRLGTH" in
*]*) COMPRESSOR=lzma ;;
*BZh9) COMPRESSOR=bzip2 ;;
*) COMPRESSOR=gzip ;;
tail -c+$[${RPMHDRLGTH%:*}+1] "$1" | $COMPRESSOR -d

Just some notes. This assumes GNU tools. Additionally it will not work with rpms that use xar instead of cpio internally.
