shell script string extension
hey,

im looking for a way of extending a string in shell script.
for example i have two strings "." and "abcd",
i need to extend the first string so that it is the same length as the second.
so "." and "abcd" becomes "...." and "abcd",

could someone shed light on how to do this ? thanks

Code:
[/tmp]$ cat try.ksh
#! /bin/ksh

f="abcd"
o="."

f_len=${#f}
o_len=${#o}

while [[ $o_len -lt $f_len ]]
do
  o="$o."
  o_len=${#o}
done

echo "$o"
echo "$f"
[/tmp]$ ./try.ksh 
....
abcd
[/tmp]$
