numbering each line in a text file
I have a simple text file.

I want to number each line in that file .

for example:

My text file is

unix
my file
test


My output should be

1 unix
2 my file
3 test

nl myfile

Code:
# number each line of a file (simple left alignment). Using a tab (see note on '\t' at end of file) instead of space will preserve margins.
sed = filename | sed 'N;s/\n/\t/'
# number each line of a file (number on left, right-aligned)
sed = filename | sed 'N; s/^/     /; s/ *\(.\{6,\}\)\n/\1  /'
# number each line of file, but only print numbers if line is not blank
sed '/./=' filename | sed '/./N; s/\n/ /'
