Re: adding data to a file before it gets regexed

Thanks Chas for the reply

what I'm trying to do is add the file name to the start of the string beign
placed in the array, I havent used hashes so I'm not fiormlar with using
hashes, but I am open to using them.

The reasion I am trying to add the string to the line, is so that I can use
it in a regex afterwards, so it will break out what file was assiated with
the line, as I have a list of files that i am adding together.
I'm using opendir to get a list of files, then opening the files using open,
but I want to add the file to the string.

Thanks
Pat

hi all
I have the following problem.
I'm trying to read the a file in line by line. using a for each
statment,
but I want to modify each line as it come in so that I can add the file
name that I am looking in to the line.

eg. looing in file1.txt we have the line "hello world"

I want to do the following:
hello world
becomes......
file1.txt hello world

I don't understand what you are trying to accomplish. Are you trying
to modify the original file or just store files data in your program
with the files name attached? If you are trying to do the latter then
it is not a good idea to store entire files in memory and it is really
not a good idea to add the file name to each line of the file. A
better design would be a hash of filehandles whose keys are the names
of the files you want to read from, or, if you really need to store
the files in memory, a hash of arrays whose keys are the filenames and
the arrays are the contents of the files broken down by lines.
