What Others Think

TODO: - Give more weight to vowles - Make paragraphs start with a tab. - Remove 2,3 consonates togheter.

I wonder where can this command show its usefulness.
willcai · 666 weeks and 3 days ago
Interesting and as willcai points out probably not very useful :-) However, we can tidy it up a bit: First, the middle two tr commands can be combined: ... | tr 0-9 '\n ' | ... Zero will be converted to a newline. 1-9 will be converted to space. Next, shorten the sed command. There won't be any tabs in the output, so: ... | sed 's/^ *//' | ... Leaving: tr -dc a-z0-9 </dev/urandom | tr 0-9 '\n ' | sed 's/^ *//' | fmt -u I've been trying to make the output more realistic by skewing the random input. No success so far :-(

Here's a quick sed to remove any duplicate letters: ... | sed 's/\(.\)\(\1\)*/\1/g' | ...

I think this is useful to create "Lorem Ipsum"-Text. And no, you can't combine the tr-commands. Try ...tr 0-6 \ | tr 7-9 \\n ... to see the difference. Changing the ranges influences the length of the generated paragraphs.
joedhon · 666 weeks and 3 days ago
Rigth joedhon!. Numbers are used to parametrize spaces/newlines, although flatcap solution is more elegant and you can also parametrize this way: ...tr 0-9 " \n" so 0-6=" " and 7-9="\n". right ? Thanks all!
rubenmoran · 666 weeks and 2 days ago
No, that is 0-9="\n", and the lines having trailing spaces. btw: there will never be a "." , so the -u is unnecessary unless you throw in some extra dots and spaces after the dots.

Perfect House Of Pugs acquired a passion for animals, and the Pug puppy in particular, at a young age since I grew up in a house with lots of dogs. It was a natural ability to know how to grow, nurture, and care for animals. I knew what the future held when I met my wife, who essentially had the same enthusiasm as I have. Being a breeder is more of a passion for me than a profession since I get to witness people's faces light up when they successfully adopt a pug puppy from our facility. It is not possible to find happiness in anything else. PLEASE VISIT OUR WEBSITE LINK BELLOW FOR MORE INFORMATION ABOUT PUG PUPPIES.
