1st qestion:
awk '{print NR,$0}' urfile > newfile
or awk '{printf("%-5d%s\n",NR,$0)}' urfile >newfile (better looking)
or grep -n "" urfile > newfile
2 question:
when you print file, you could setup print configuration.

来自主题: Unix版 - how to let awk not print?

awk '!/^$/' urfile
perl -pi -e 's/^$//g' urfile
sed -ne '/^$/!p' urfile
if using tcsh/csh, be careful of using !
