The awk program stores the current line in variable $0 and the record number ("line number") in NR. This command will print the lines with a line number appended:

awk '{ print $0, NR }' yourfile.txt

For prepending line numbers, there also exist the nl command ("number lines of files"):

nl yourfile.txt
