Re: delete empty lines from a txt file

You'll be wanting to use that lovely inplace edit switch -i

perl -i -ne 'print unless /^\s+$/' your_file.txt
[download]

For more info on that ever-handy switch checkout perlrun.

Notice that broquaint also sneaked in the `-n` flag there. That's the one that actually sets up a loop that processes the file a line at a time. And just to be obtuse, I'd write it like this: `perl -i.bak -ne 'print if /\S/' your_file.txt` [download] -- <http://www.dave.org.uk> "The first rule of Perl club is you don't talk about Perl club."
