Given that the sample output you provided is not formatted at all like you said you wanted and, instead, just changes the <comma>s in your CSV file to <space>s; I don't know whether you want the input data to be left-justified in the output or right-justified.

Assuming that you want left-justified text in your twenty character and ten character output fields, two (of many) simple ways to do what you want include an awk script:
Code:
awk -F, '{printf("%-20.20s%-10.10s\n",$1,$2)}' file.csv

and a shell while read loop:
Code:
while IFS=, read c i
do	printf '%-20.20s%-10.10s\n' "$c" "$i"
done < file.csv

if you want right-justified text instead of left-justified text, remove both of the minus signs from the printf format strings in either of the above scripts.
