Try with printf:

 for((i=32;i<=127;i++)) do printf \\$(printf '%03o\t' "$i"); done;printf "\n"

Or, the same idea, using a differnt way to get the octal value: for((i=32;i<=127;i++)) do printf "\\$((i/64*100+i%64/8*10+i%8))\t"; done;printf "\n" ... –  Peter.O Jun 17 '11 at 19:34
    
Or using the bash builtin echo... for((i=32;i<=127;i++)) do eval echo -ne $\'\\$((i/64*100+i%64/8*10+i%8))\'"\\\t"; done; echo –  Peter.O Jun 17 '11 at 20:40

You can do:

man ascii

to see the whole set of ascii characters.

More an awk solution that a (pure) shell one but here it is anyway:

awk 'BEGIN{for(i=32;i<128;i++)printf "%c",i}';echo
