Re^4: Programs that write programs

<snark>

$ perl -e''
No code specified for -e.

</snark> :)

Update: Hm, seems to work fine with a file:

$ perl -w /tmp/empty.pl

Update 2: Nevermind, moritz is a clever boy, and laziness (leaving out whitespace) is not always a virtue.

Update 3: I think I prefer the symmetry and perl purity of: echo -n | perl | perl | perl | echo -n

[moritz]

$ perl -e ''
$

If you leave out the space, the shell just eats the quotes, but doesn't create an empty string to pass on to the perl binary.

$ perl -e '' | perl | perl | perl
