How do I grab the first 10 characters of a line and append it to another empty file?

Some ways:

Code:

$echo ${string:0:10}

Code:

 echo $string | awk '{print substr($0,1,10)}'

Code:

 echo $string | sed 's/\(.\{10\}\).*/\1/'

Next question how do I remove the first 10 characters and leave the rest of the filename?

Is this a riddle, what are you trying to achieve? Or is it homework?

I don't have home work, it's been years since I have.... just new to this group and figuring out bits and pieces...

Ok, but do you understand how the given code works? I should read some books or Google for some tutorials.
Anyway, to answer your question, some things to unravel:

Code:

echo ${string:10}

Code:

 echo $string | awk '{print substr($0,10)}'

Code:

 echo $string | sed 's/\.*(.\{10\}\)/\1/'

Regards
