Hi,
I am trying to read data from a file, I do this by using the "while
(<FILE>){ $line....}" construction.
However with files with a size of roughly bigger than 430MB it seems to
crash the script :S Syntax seems all fine (perl -wc -> syntax OK).
I was thinking that maybe it was running to the end of a 32 bit counter
(but that would be 536 MB right?)? Can anybody offer an other solution
to work with such large files and perl?
No idea, a little script sample might be good.
While running my script it seems to use around a gigabyte of memory
(there is 1GB of RAM and 1GB of swap in the system), might this be the
problem?
The script below gives the error:
#!/usr/local/bin/perl
##
#
use POSIX;
my $inputFile = $ARGV[0]; #file we are
reading from
my $outputFile = "./tmp/overall-memory.dat";
my %somestorage;
my $linecounter = 0;
my $value=40;
my $bool = 0;
open(INFILE, "$inputFile") or die("Could not open log
file."); # open for input
open(OUTFILE, ">$outputFile");
foreach $line (<INFILE>) {
$somestorage{$linecounter}=$value;
$linecounter++;
}
close(INFILE);
close(OUTFILE);
print $linecounter;
system("pwd") == 0 or die "system failed: $?";
#wc -l samples/1169209055.trcxml

# ./sample1.pl samples/1169209055.trcxml
5198365system failed: 0 at ./sample1.pl line 22.
Any ideas how to solve my problem?
Tnx!
