( #3333=superdoc: print w/ replies, xml ) Need Help??
when I am running the perl script where I user foreach to read the file line by line I got the print message. "Use of uninitialized value $site in concatenation (.) or string at logfile.pl line 13, <LOGFILE> line 19."
#!/usr/bin/perl -w use strict; use warnings; my ($time, $site, $logName, $fullName, $date, $gmt, $req, $file, $prot +o, $status, $length); $site; my $LOGFILE = "config.txt"; open LOGFILE,"$LOGFILE" or die "cannot open file : $!"; foreach my $line (<LOGFILE>) { ($site, $logName, $fullName, $date, $gmt, $req, $file, $proto, $status, $length) = split(' ',$line); my $a = "$site\n"; print "--$a\n"; my $b = "$logName\n"; print "==$b\n"; } close(LOGFILE);
Please let me know where I am doing the mistake.
