I'm quite confused that the 'difficult', as in structured, output is printed increadible fast, where as the 'long single string' takes that long.
I tried a bit and.. well you not gonna like it...
I actualy just commented out all your translating, so the script ends alot faster.
Code:
#!/bin/bash
# hex.sh </full/path/to/filename>

....
while read -s -d '' -r -n 1 char
do
subscript=0
count=0
while [ $count -le 255 ]
do
...
count=$((count+1))
if [ $count -eq 256 ]
then
#echo -n "0A "
break
fi
done
done < $1
IFS="$ifs_str"
exit
What i do not understand is, how do you get it formated in the first place?
Is that read doing it?
Not sure if this could be displayed on a moblie phone display.

echo `echo ` doesn't echoes anything. And it's logic. But
echo `echo `echo ` ` does echoes "echo". What's the logic of it? the `echo `echo ` inside of the whole (first) echo, echoes nothing, so the first echo have to echo nothing but echoes "echo"
