Hi Willy,
What does push and what is $_
That will probably be your question.
Here is one example :
open(FH, "< $file");
while <FH> { ## <FH> is the File Handler we just openened with open
## We do something with ??
## Yes, no var is set but instead we use $_ for the current line.
## Now we can set a condition, and if $_ matches the requirement
## I want to store this line into a seperated array :
if(m/mymatch/g) {
## You don't have to specify the $_ anymore as this is default (I heard).
## Now we have the line that matches our key and I want to store it together
## with all the other lines in the document that contain this searchstring
## So :
push @mymatches, $_ ; ## Or of course: push(@mymatches, $_);
## We just pushed the current line (of the while <FH>) into the end of our
## array @mymatches
} ## And of course we close our if-statement
} ## And we close our while statement
Hope this explaines your questions.
