Hello,

how about the following?



#!/bin/bash
#$1 is the input file
#USAGE scriptname <FILE_TO_COMPRESS>


#create the compressed binary
bzip2 -c $1 >temp.dat

SIZE=`find temp.dat -printf "%s"`

#create the combined shell script and binary
echo -e "#!/bin/bash\nUNCOMPRESSED=$1\nSIZE=$SIZE\ntail -c $SIZE $1.bin\ 
 > temp.bz2\n bunzip2 -c temp.bz2 > new_hello\nchmod +x\ 
new_hello\nexit\n" > temp.txt

cat temp.txt temp.dat > $1.bin
chmod +x $1.bin

rm temp.* -f
