Generate 1 digit, in a loop which runs 8 times.

It would take 5 seconds for you to try it - so why haven't you?

Well the 'my' exists inside a { } scope, so I guess it goes out of scope when the block exits.

- did you actually open the file?
- does the file you actually opened contain any data?
- does another approach to reading the same file yield data?

Getting kinda bored with your approach.

Well we could guess, or you could post code.

So are you in control of either the producer or consumer, source code wise?

Is the producer a perl script?

One while loop to input a guess, then 3 tests.

Post your code.

You also need to print the result, say

print "$_";

First thing you need to search for is all about the array @ARGV

Open each one of them in turn?
Or open many of them at once?

If you list the files on the command line, then...

Sure,

Try to reply to existing threads which cover basically the same topic as before.

In your loop, having worked out...

Well \d+\.\d+ would match a single floating point number in non-scientific format.

Sure, you should be able to do something like that.

I don't see why you need to read the whole file in, or store the whole file before writing it out.

chomp;
my @f = split; # splits $_ at white-space
print DAT $f[0] ....

Replace
file.txt
with
*.txt

awk reads the file even more implictly than perl does. So implicitly in fact that you don't have to say anything at all.

About the same as you would perl, except you type 'awk' instead of 'perl'

Along with 'sed' and 'grep', they form a family of text processing...

Edit your post so your code is readable, and not munged by smilies and zero indentation...

Ok, before everyone gets bored with yet another round of "20 questions", do you use some pre-defined API to get a file for you, even if you're not directly responsible for opening files?

Have you...

First random guess is you've reached the max number of open files you're allowed to have because you're not closing any of them.
