Hi all,

How about doing the reverse way?
For EG,

I need a 2 character numeric term all the time.

7 ->change to -> 07
8 -> change to -> 08
10 -> No change -> 10

This is a great command.
What if the text string contains alphanumeric characters before it?
I was trying to get this to work, but was unsuccessful.

I'm not sure, do you mean this?

Code:
% printf "%s\n" 0011myfile myfile00220 my003303file|sed "s 00*\([1-9]*\) \1 "
11myfile
myfile220
my3303file
%
