Like this?
echo "12345" | sed 's/./&./g;s/\.$//'
1.2.3.4.5
Try like..
echo "12345" |sed 's/./&./g;s/.$//'
thanks.. got it working using either:
$ echo '12345' | sed "s/./&./g;s/\.$//"
1.2.3.4.5
$ echo '12345' | sed "s/./&./g;s/.$//"
1.2.3.4.5
One more
echo "12345" | awk -F "" ' {for(i=1;i<=NF;i++){printf("%s%s",$i,i%1?"":".")}}'|awk '{sub(/.$/,"")};1'
Some awks can do this:
echo "12345" | awk '$1=$1' FS= OFS=.
Slight modification to Scrutinizer's solution to handle the case of strings starting with zero:
echo "12345"| awk '{$1=$1}1' FS= OFS=.
In perl:
$ echo '12345' | perl -pe 's/(.)(?!$)/\1./g'
1.2.3.4.5

Search for characters that are not followed by the end of the line, and add a period after them.
