Q&A > strings > How do I compare two strings? - Answer contributed by PipTigger

As an addendum to turnstep's fine post: Another useful test is: ne ... as in:
if ($string1 ne $string2) { print "\$string1 is not equal to \$string2\n"; }

Just as: == tests equality between two numbers,
!= tests inequality for numbers and
eq tests strings for equality as
ne tests strings for inequality.
I often find it useful to test
if ($string0 ne "") { #use $string0 }
to verify that a string has a value even if it's == 0.

[marto]: hopefully next year I'll be in a position to go to Perly things in Europe :)
[Corion]: Maybe I'll use the Real Jekyll a bit to get a feel for how it actually works, and to get annoyed by it ;)
[Corion]: marto: That would be cool :) There is no kids care at Perly events unfortunately, so it's not entirely family friendly
[Corion]: I think I should define a set of (say) five projects through which I rotate from time to time, just to prevent myself from being bored/annoyed by the problems they get stuck in ;)
[marto]: Corion, not bringing the kids would make it ideal :P
[marto]: a suggestion, have one project in the list that isn't programming/perl related
[Corion]: marto: Yeah, things are more parent-friendly the way they are ;))
[marto]: some hardware/makey thing
[Corion]: marto: Ah, I'm currently drifting to that again, over"painting" (well with Inkscape) one of my photographs and thinking about vectorizing some other images ...
[marto]: Corion, yes something 'artistic', so that or some music. Even combine some things, build a musical instrument :)
