franklin,

sed 's/^./ /', your command would do the same thing?

thanks.
Code:
 sed "s/A2009/ 2009/g"

Your command replaces every "A2009" in a line, not only on the first position.
To match the pattern "A2009" at first position of a line, add a circumflex "^" at the begin of the pattern:

Code:
sed 's/^A2009/ 2009/'

This command:

Code:
sed 's/^./ /'

replaces every character at the begin of a line with a space.

Regards
