Last 10? or start from? Proper grammar would help here.

Remove last ten characters on all lines from the third through the end:

Code:

sed '3,$s/..........$//'

say I have a line:
blablabla
blablabla
asdfasdf0123456789
asdfasdf0123456789

I want the out put to be:
blablabla
blablabla
asdfasdf
asdfasdf

thank you

And the stuff about the third line was just to confuse the enemy? Did you try the script I posted? You can probably adapt it if it doesn't do exactly what you mean.

sorry, I meant

a file:
blablabla
blablabla
blablabla
asdfasdf0123456789
asdfasdf0123456789

output:
blablabla
blablabla
blablabla
asdfasdf
asdfasdf

You didn't try the script, and are unable or unwilling to make a trivial modification to it?
