Thanks! It worked! If you don't mind, I have one more question. I need to use a similar sed command to filter out this kind of data:

Code:

 1246346269-d1989834dbd34170e1a29310191e9dcf63538368202ee72eae62d

I can modify the one you provided right? For instance

I know

Code:

's/\([0-9a-f]\

is the first 8 digits including letters,

Code:

 {4,\}-\)\{4\}

is the next 8 digits with the dashes, and

Code:

[0-9a-f]\{12\}//g'

is the last 12 characters; correct? so the code would be something like

Code:

 sed -e 's/\([0-9]\{10,\}-\)[0-9a-f]\{53\}//g'

?
