removing spaces in the file starting at certain line number

[Pando]

dear gurus,

I have a file that needs to be stripped of spaces beginning at a certain line. For example, i need to strip only the white spaces beginning at line 10. I have found a perl script in this forum but it strips of the white spaces of the whole file. What i need is to strip white spaces beginning only at a certain line of my file.
Maximum points to all correct replies.
Thanks!

use
sed '10s/ //g' file > outputfile

Fernando,
I believe Rajeev's solution should have been:
sed '10,$s/ //g' file > outputfile

The first part of the sed command in the original post would only replace spaces in line 10, whereas 10,$ means lines 10 to the end of the file.
