Unix Tip #4613- October 28, 2025
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
