changing the first occuence in a file using sed

[RJSHA1]

Hi there,
I have a file with the following layout :-

Header
Data
Trailer

I want to append a sort code to the hader so that the file looks like this

Header123456
Data
Trailer

I have tried sed 's/$/123456/' file1 > file2

but I get

Header123456
Data123456
Trailer123456

What am I doing wrong


Thanks Bob....

Try

awk 'NR==1 {print $(0)123456;next} {print}' file1 > file2

Try something like this:

sed '1s/$/123456/' file1 > file2

Hope This Help

Hi guys,
Both solutions work. Thanks for your help. I have one other question, will the end of line character still be left on the 1st line


Once again thanks for the help
