in reply to Output split over two lines

perl is doing what you told it to do:
my $yen = <STDIN>;

Now the "\r?\n" is still attached to the contents of the variable $yen. You want to say

chomp(my $yen = <STDIN>);

See chomp and chop.


See also perlvar for $/.



update: changed "\n" to "\r?\n" above, and /s/chop/chomp/, since chop chops one character, while chomp removes a trailing $/ (which might be "\r\n" or "\r". Thanks to ikegami for telling me in a /msg.

[Lady_Aleena]: Um, how does grep do multiline? print "$file:$_" if grep { /get_(array|hash| data)\(.+\)/ } $_; only returns the same 18 lines the command line grep does.
[Lady_Aleena]: my scratchpad has what I have so far.
[choroba]: what do you mean by multiline?
[Discipulus]: thanks 1nickt!
[choroba]: grep is a filter, it selects elements from a list based on a boolean condition
[moritz]: you need to read the file in one go to do a multiline regex match
[erix]: ha ha, I like the Vigilante
[Lady_Aleena]: Forget it. I'm getting angry with it.
