Shell Programming and Scripting

I have a file say "codefile" here ,contains data like this

Hi! How are you?

I need to covert this data into stram of equivalant ASCII values

I wrote follwoing script.

#!/bin/bash
while read -n1 char
do
printf "%d" \'$char
done < codefile

this gives me output

./coder.sh
7210533072111119097114101012111111763


it has printed sapaces as 0 (Blue coded) which is suppesed to be 32(equivalant ACSII for space)

Please help

Add quotes round the $char in your printf

I added

#!/bin/bash
while read -n1 char
do
printf "%d" \'"$char"
done < codefile

------------------------------
But no change in output ,tried adding $"char" also but no go.

./coder.sh
72105330721111190971141010121111117630

Hmm, adding the quotes allows a space to be converted (before that it was treating it as null)
But the read is also turning the space characters into nulls (to see this, add echo "\"$char\"" before your printf).
So, we'll switch to using something else like cut:

Code:

#!/bin/bash
while read line
do
        while [ -n "$line" ]
        do
                char=`echo "$line" | cut -c1`
                line=`echo "$line" | cut -c2-`
                #echo "\"$char\""
                printf "%d" \'"$char"
                #echo ""
        done
done < codefile
