Unix Tip #4378- March 7, 2014

LINE NUMBERS IN LINUX



If you want a file with line
numbers (say for printing).
You can use the "nl" command
in linux.

$ nl file.c > file.c.num

See man for more options.
Normally nl gives line numbers
only for non blank lines.

To force it to give it to all lines
use -ba option:

$ nl -ba file.c >file.c.all_num
