I want to delete initial N bytes of a file using sed.
How can I do that?

2

sed 's/^\(.\)\{11\}//g' forsed

This would help in deleting 11 bytes from the begining of a line, i assume u are not working on binary(I fear about endian issues).

This one is a generic u can adapt to your need, like for a line or more or specific line etc.
I am not whether this is what u require

Hope this helps

sed 's/^\(.\)\{11\}//g' forsed
will delete the first 11 characters from each line

sed '1s/^\(.\)\{11\}//g' forsed
will delete the first 11 characters from the first line but the first line must contain 11 or more characters

Ignoring line boundaries will be hard using sed. To ignore line boundaries and simply delete the first n characters you might want to consider switching to dd.
