Removing blank lines

[Robert Klemme]

Yep!

ruby -i.bak -ple 'next if $_==""' test

Inplace editing with backup file.

Without inplace editing

ruby -pne 'next if /^\s*$/' test
ruby -ne 'puts $_ unless /^\s*$/' test

Kind regards

this thread (and the removing duplicate lines thread) are a good
example of ruby's tim toadie.

i would have probably come up with the a variation on the gsub examples.

I would call it more of an example of TIMTOWTDI for *n*x in general.
You can write a short script in any number of languages, or use any
number of already built tools (awk, grep) to do it. Myself, I'd just
use my trusty old grep (I'll concede it's not readily available on a
default windows install).

for the most part i DO know my tools. that's why i have to reinvent
some of them. although mostly on the windows side

LOL

Adding to that: at times it's just fun to reinvent some of the weels...
