Re^3: IO::Handles ... any good?

Currently I only have this solution for a single file:

perl -pe '$_.="\n"' file1.txt > file1.new

It's untested but should read file1.txt and print the modified version into file1.new.

I have no idea, how to perform this with multiple files in one (simple) command.

You could still use a shell for loop to perform this upon several files...

# bash
for FILE in *.txt; do perl -pe '$_.="\n"' $FILE > $FILE.new; done

Windows shell would be `for %q in (*.txt) do perl -pe"$_.=$/" "%q" > "%q.new"` [download] And a golfed version would be `perl -nEsay # 5.10 perl -pe$_.=$/ # <5.10 Windows perl -pe'$_.=$/' # <5.10 bash` [download]	[reply] [d/l] [select]
