I wonder where can this command show its usefulness.
willcai · 378 weeks and 4 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.

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 · 378 weeks and 3 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.
