perlopentut - simple recipes for opening files and pipes in Perl. DESCRIPTION. Whenever you do I/O on a file in Perl, you do so through what in Perl is called a filehandle. A filehandle is an internal name for an external file. It is the job of the open function to make the association between the internal name and the external name, and it is the job of the close function to break that... A quick way to get the number of the last element in a Perl array is to use $#array_name notation. For instance, if you have an array called @test, the index of the last element is $#test. For instance, if you have an array called @test, the index of the last element is $#test.

Perl Array Quick Guide to Arrays In Cave of Programming
In this article we are going to see how we can sort an array of strings or numbers in Perl. Perl has a built-in function called sort that can, unsurprisingly, sort an array. In its most simple form, you just give it an array, and it returns the elements of that array in a sorted order. @sorted... >I can create a hash with the key being the user's name and the value >being the number of tickets but I am not sure how I can find out who has > >the lowest number.

- In this article we are going to see how we can sort an array of strings or numbers in Perl. Perl has a built-in function called sort that can, unsurprisingly, sort an array. In its most simple form, you just give it an array, and it returns the elements of that array in a sorted order.
- In this part of the Perl Tutorial we are going to learn about some of the functions Perl provides for manipulating strings. lc, uc, length There are a number of simple functions such as lc and uc to return the lower case and upper case versions of the original string respectively.
- An array is a variable that stores an ordered list of scalar values. Array variables are preceded by an "at" (@) sign. To refer to a single element of an array, you will use the dollar sign ($) with the variable name followed by the index of the element in square brackets.
- By running a for loop and trying random values from various posts, for Strawberry Perl uname='Win32 strawberry-perl 188.8.131.52...' with known timezone bugs, any 3 chars I tried (didn't try + or -) followed by +/- and a small number worked. Here is an array of text values and their output below:
