append a sequence id to all records 2

[mwesticle]

Hi... I have a fixed-length file, and I need to append a 38-byte sequence id (starting with '00000000000000000000000000000000000001') to the beginning of each record. I know there is an easy way to do this using a korn shell script, but I can't remember it. Can anyone help me out here? Thanks!

Something like this ?
awk '{printf "%038d%s\n",NR,$0}' /path/to/input >output

That's great! One more question... How would I do the same thing on another fixed file, this time starting with '10000000000000000000000000000000000001'? Any ideas? Thanks again!

Try this -

awk {'printf "1%037d%s\n",NR,$0}' /path/to/input > output.


I am assuming that you still need a 38-byte sequence.


HTH,
