Issue the following command and be enlightend: man 1 printf Or just use 'echo' instead.

There are many ways:
echo "${raw_ip}" | sed -e 's/\.//g'
echo "${raw_ip}" | perl -pe 's/\.//g'
echo "${raw_ip}" | awk -F. '{gsub("\\.", ""); print}'

Hello,
The problem here is that single quotes ("'") avoid variable
substitution. e.g.
var="text"
echo $var # outputs text
echo '$var' # outputs $var (literally)
Also the backslash avoids variable substitution when placed before a
"$". e.g.
echo $var # outputs text
echo \$var # outputs $var (literally)
The solution is this:
ret_ob=`printf "$ret_ob" | sed "s/$std_text//g"`
^ ^ ^
Hope that helps.
Best Regards,
Ale

Use backtics: num_ip=`echo $raw_ip | sed 's/\.//g'` Note that when you do this, more that one IP address can end up as the same num_ip, e.g. 11.0.1.50 and 1.10.1.50.
