I am not sure what exactly you mean by ascii to hex and oct. Are you talking about converting a string representation like "0755" or "0x55" ? If yes, then look at oct and hex.

Otherwise maybe you want to get the ascii value of a character and represent it as oct or hex. Use ord to get the ascii value and then printf %o for oct and printf %x for hex. The formatting codes for printf are explained here

Update:

After re-reading the link you included I think I have a better understanding of what you are asking for. Some code below

octal

 perl -e 'printf("%o", ord) foreach ( split //, shift )'

hex

 perl -e 'printf("%x", ord) foreach ( split //, shift )'
