Append 0 for single digit entered from command line

namishtiwari · #1 (**permalink**) 08-24-2007

I have a script like this--

#!/bin/ksh
echo "To pad a 0 before digits from 1-9"
for i in $*
do
echo $i | sed 's/[1-9]/'0[1-9]'/g'
done

I run this script as

ksh name 1 2 23 34

The output should be
01 02 23 34

Help me in modifying this script.

Thanks
Namish

Code:

#!/bin/ksh
echo "To pad a 0 before digits from 1-9"
for i in $*
do
   printf "%02s\n" $i
done

Code:

#!/usr/bin/ksh
echo $* | sed 's/ \|^/  /g ; s/[^1-9]\([1-9]\)[^1-9]/ 0\1 /g; s/  / /g'

should work too
