Hi,
Writing output to file depends on what format you want to write.
Here is the simple script to read lines and seperate all the fields.
my $filename = "data.dat";
my @fields;
open(FILE, $filename);
my @data = <FILE>;
close( FILE);
foreach my $line (@data) {
@fields = split(/\|/,$line);
#uncomment the line below to print fields.
#print "$fields[0], $fields[1], $fields[2], $fields[3], $fields[4] \n";
}
Regards,
Yogesh
<Added>
Add one more line... chomp($line); in foreach loop before splitting to remove new line charecter.

Hi yogeshate,
Thanks for your reply.
If this is continuous file format in which sending to one certain location path. How should it be handle?
For example,
001.txt
002.txt
003.txt
:
:
These files will have the content mentioned in my 1st post.
Besides, if I want to display them to output such as
a=046437463
b=Yes
c=Yes
d=Yes
e=Yes
Please advise. Cheers

Hi again,
Try this if you are sure of all .txt files are to be opened.
@files = `ls *.txt`;
foreach my $filename (@files) {
open(FILE, $filename);
@data = <FILE>;
close( FILE);
print $filename.@data."\n";
foreach $line (@data)
{
chomp($line);
@fields = split(/\|/,$line);
print " a=$fields[0]\n b=$fields[1]\n c=$fields[2]\n d=$fields[3]\n e=$fields[4] \n";
}
}
Else
Try this:
my $filename;
my @fields;
my @data;
my $line;
my $limit=100;
my $start=0;
my $f_prefix;
my $f_sufix = "/forum/.txt";
while($start<=$limit) {
if(length($start)==1) {$f_prefix="00".$start;}
if(length($start)==2) {$f_prefix="0".$start;}
if(length($start)==3) {$f_prefix=$start;}
#Add more if conditions $limit is above 1000
$filename=$f_prefix.$f_sufix;
if (-r $filename) #if file exist in the current directory
{
open(FILE, $filename);
@data = <FILE>;
close( FILE);
print $filename.@data."\n";
foreach $line (@data)
{
chomp($line);
@fields = split(/\|/,$line);
print " a=$fields[0]\n b=$fields[1]\n c=$fields[2]\n d=$fields[3]\n e=$fields[4] \n";
}
}
$start=$start+1;
}
Regards,
Yogesh
