Interesting perl One-liner
How do you double space every line in a file.I mean add an extra newline in between files.I would have done this below:
perl -pe 's/$/\n/' your_file
I also feel that this is a clean way to do.Use a regex,replace every $(end of line) with a new line.
well there is a much coller way i found,
do you know that there is awk's ORS equivalent in perl too?
yes there is.
$\ in perl = ORS in awk
so now if i do the below,it does the same thing as the first command i mentioned at the top.
perl -pe '$\="\n"'
