in reply to perl-5.8.0 print statement

It's because you aren't printing a newline after the output, which operating systems like linux require. Two ways to fix it. The easiest is to add the -l switch to perl: perl -le "print crypt('string', 'salt')". The second way is to print out a newline as well (less-cool :P): perl -e "print crypt('string', 'salt'), qq{\n}".

    Sorry, that's wrong. There's no such requirement. Observe: 

    bash$ uname -a
Linux amano 2.4.18-3ntfs #2 Sun Jun 9 12:40:53 PDT 2002 i686 unknown
bash$ perl -e "print crypt('password','A0')"

    It may look funny, but it'll print just fine regardless of whether there's a newline or not.

      s/linux/Windows sometimes/ makes that statement correct. Though I've never figured out the details of when the missing newline presents a problem.

      I've also seen Unix shells configured with "\r" at the start of their prompts which could hide the fact that the crypted string was output.

      Mmm... I suppose it really does depend on the environment in which you are working. Or... what Perl version do you have installed? I've never had to add the newline in Windows XP. In any case, there are times when the newline is required. I don't know the conditions under which it is necessary, but I bet that it's the correct answer to the original poster's question. BTW, here's the output I receive: 

      [root] perl -v
