Replacing leading zeros with leading spaces

deepakwins · #1 (**permalink**) 06-17-2008

Hi,
May i know how to replace the leading zeros with leading spaces.

eg:

Input
------
001235
000012
005655

Output
-------
1235
12
5655

Question 2:
How to transform the same output as follows

1235 *****
12 *****
5655 *****

Where *'s are some other value part of record.
The first field that requires the transformation is fixed say 6 digit as in this example('1235 ').

You ask about leading spaces but your example shows no leading spaces. Which do you want?

For question1 try this:

cat a.txt | sed " s/^0*//"

awk '{printf("%6d\n",$1)}' <file.txt

This will trim all the leading 0's. But my requirement is different.
