Appending text to the lines in the file

[dwgi32]

Hi,

I am trying to appending additional text to every line in a text file, can anyone advise me how to construct a ksh script, thanks!

a.txt
------
045345
23455

i want to append "My menu id is :" to every line in a.txt. Desire result:

a.txt
-----
My menu id is : 045345
My menu id is : 23455

Thanks

sed  's/^/My Id is: /' file > newfile

awk '{print "My id is "$0}' file > newfile
