question on inverting text -> txet

[arctan]

Hello Group

I was wondering in anyone knew of or could generate a script that
takes an input file which consists of one long line of charachters,
and would output the file inverted (backwards)

i.e. input file looks like: opkiltyo
output file looks like: oytlikpo


Thanks alot in advance for any help offered.

A hint:

print scalar reverse split //, 'opkiltyo';

A hint:

print scalar reverse split //, 'opkiltyo';

Kind of a confusing hint...

# in scalar context: reverses a string
print scalar reverse 'opkiltyo';

# in list context: reverses a list
print reverse split //, 'opkiltyo';

Not that your code doesn't work -- just that it works for an odd
reason. After you split() the characters, reverse() concatentated
them back together and treated them like a scalar.

Hmm.. I think I misread the docs. Thanks for pointing it out.

perl -lpe '$_ = reverse'
