-pe
‘gsub!(/\w+/){|w|r=1…w.size-1;w[r]=w[r].split(//).sort_by{rand}.to_s;w}’
Hmmm … This seems to smbrcale all the lertets but the fsrit. It souhld
lvaee the last ctaeachrr in pclae.
Try:
ruby -pe
‘gsub!(/\w+/){|w|(w.size>1)?(r=1…w.size-1;w[r]=w[r].split(//).sort_by{rand
}.to_s;w):w}’
It’s leongr, but it gevis the rihgt asnwer.

Oh yes, I got size-1 wrong:
-pe ‘gsub!(/\w+/){|w|r=1…w.size-2;w[r]=w[r].split(//).sort_by{rand}.to_s;w}’
It seems there is no need to treat the case w.size > 1 specially because the
slice gives an empty string for sizes == 1 or 2 and everything seems to work
right AFAICT.

In Perl, the criosomapn fnutcoin uesd by srot() is rreqeuid to behave
cisnotsltney, so tihs seohtrr one-lenir may not be ksoher:
-pe ‘s!\B\w+\B!join"",sort{.5>rand}$&=~/./g!ge’

Right. That’s also true of the block passed to Ruby’s Array#sort
method. The one-liner users Array#sort_by, whose block is used to
assign a key to each array element. It’s basically a shortcut for
a Schwartzian transform:
x = y.sort_by { |i| z(i) }
is roughly equivalent to this Perl code:
$x = map { $_->[1] }
sort { $a->[0] <=> $b->[0] }
map { [z($_), $_] }
