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

Depends on what kind of comparision: Strings can be tested for the following
Equality - the eq operator
Inequality - the ne operator
Greater Than - the gt operator
Greater or Equal - the ge operator
Less than - the lt operator
Less of Equal - the le operator


Syntax:
$stringtest = ($string1 eq $string2);
Try replacing eq with the other operators.

    The inequality operator is ne.

[Corion]: marto: How's things? I hope the kids are fine and you too!
[Corion]: Oh yay. I wonder why a very simple change in a program doesn't elicit a diff, and now I see that my diff program seems to have a bug ;)
[1nickt]: marto thanks for asking, so far so good. A pretty modern stack and decent procedures, although rather too much home-built stuff (e.g. a logging role that should tries to duplicate Log::Any).
[Corion]: No. It's just that I'm comparing the same output file twice, instead of comparing the output files of the two runs %-)
[Corion]: Lo and behold, running a program with the correct input files yields the correct (and expected) output. Yay me.
[1nickt]: Got a MacBook and am expected to develop directly on it, ironic given the recent thread about that.
[marto]: Corion, some not too serious issues with the kids, hopefully, other than that just dealing with commuting by car again in the winter, not much fun so far, and there's no real 'bad' weather yet :)
[marto]: 1nickt, glad to hear it, I'm sure you'll bring improvements to their stack in due course ;)
[1nickt]: Just trying to adjust to a new culture. Better doc than I am used to , but quite a bit more Agiley meta-bullshit; at least half a dozen meetings a week, strict "sprint" schedule etc. I'll adjust. And I hope to just switch off after the "scrum" each day at
[1nickt]: ... the end of the afternoon. marto How are you, snowed in? Mum and Dad expecting snow today in Surrey. (Have 5" on the ground here in NJ. And my son's high school in SOCal closed until after Xmas due to fires.)
