NUMBERING A FILE

Ever want line numbers
appended to a file. Here
is a short script.

awk '{no=no+1; printf"%d : %s", no, $0}' filename > filename.out

Another shorter but not
necessary elegant method
is:

grep -n . filename > filename.out

filename is the original file
filenmae.out is the file with
line numbers appended at the
beginning of each line
