Add line number count as C-style comments

awk '{printf("/* %02d */ %s\n", NR,$0)}' inputfile > outputfile
I often find the need to number enumerations and other lists when programming. With this command, create a new file called 'inputfile' with the text you want to number. Paste the contents of 'outputfile' back into your source file and fix the tabbing if necessary. You can also change this to output hex numbering by changing the "%02d" to "%02x". If you need to start at 0 replace "NR" with "NR-1". I adapted this from http://osxdaily.com/2010/05/20/easily-add-line-numbers-to-a-text-file/.
Sample Output
/* 01 */ first
/* 02 */ second
/* 03 */ third
/* 04 */ fourth
/* 05 */ fifth
/* 06 */
/* 07 */ seventh
