Hi folks:
I first want to apologize for this post. I think that during the fall
back, I lost a few brain cells.
I am working on a Perl script to update a data file. I load my data
into an array. I want to cycle through the array and make changes. Then
output the array to a file. In the past, I would open the database,
read in the lines, and output each line as I updated the elements in the
array. In these scripts, I was only updating, one element in the array.
Now I need to update several elements in the array before writing
everything to a file. If I write the program as I have in the past, I
would be using a lot of i/o reading the data into the array, changing
one element and then outputting the data to a file and repeating the
steps over and over until all the changes have been made. In some
cases, I will be changing 20 to 30 elements in the array. So I need
some help.
I read in an array from a file. It looks something like this:
200044455669,,abcdefg,7777777,f00,f00,f00,f00,a01,b23,c45,d00,e10,no,no,no,no,no,
200011122333,,hikls,2222223,f32,f43,f00,f00,a04,b06,c08,d03,e09,no,no,no,no,no,
mrgreenjeans,,pqrstuv,44442244,f20,f00,f00,f00,a06,b08,c10,d10,e00,no,no,no,no,no,
20006654987,,zzzxyxz,33344434,f03,f00,f00,f00,a00,b12,c12,d13,e14,no,no,no,no,no,
Each line represents one element in the array.
So $array[0] equal
200044455669,,abcdefg,7777777,f00,f00,f00,f00,a01,b23,c45,d00,e10,no,no,no,no,no,.
I want to update the 4th, 5th, and 13th subelements in $array[0],
$array[1] and $array[4]. Then I want to write the updated @array back
to a file.
Can some one shed some light on how I can do this without updating a
single line at a time?
Thanks.
