I wonder where can this command show its usefulness.

Comment by willcai 222 weeks and 2 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' | ...
Comment by flatcap 222 weeks and 2 days ago

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.

Comment by joedhon 222 weeks and 2 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!

Comment by rubenmoran 222 weeks and 1 day 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.
