Hi,
Hello,
Can anybody tell me why its not printing the contents of each
inside a particular folder ?
Yes I can, and so can Perl's documentation:
perldoc -f readdir
my $tstToRunDir = "C:\\perlScripts" ;
my $fileInTstToRunDir ;
opendir TST2RUN, $tstToRunDir || die "Failed to open $tstToRunDir $!\n" ;
open RESULTS_LOG, ">>ResultLog.log" || die "Failed to open log\n" ;
The logical or operator '||' has relatively high precedence so neither opendir
nor open will die if an error is encountered. You need to either use parentheses:
opendir( TST2RUN, $tstToRunDir ) || die "Failed to open $tstToRunDir $!\n" ;
open( RESULTS_LOG, ">>ResultLog.log" ) || die "Failed to open log\n" ;
or use the low precedence 'or' operator:
opendir TST2RUN, $tstToRunDir or die "Failed to open $tstToRunDir $!\n" ;
open RESULTS_LOG, ">>ResultLog.log" or die "Failed to open log\n" ;
while ($fileInTstToRunDir = readdir (TST2RUN)){
chomp $fileInTstToRunDir ;
$fileInTstToRunDir comes directly from the file system so there is no reason
to use chomp.
#open the file and get connection description and test description
open FILE_2RUN, $fileInTstToRunDir || die " Failed to open
$fileInTstToRunDir:$!\n" ;
Again, there is a precedence problem with the '||' operator. The file name in
$fileInTstToRunDir was obtained from the $tstToRunDir directory so you need to
include the directory name in order to access it:
open FILE_2RUN, "$tstToRunDir/$fileInTstToRunDir"
or die " Failed to open $tstToRunDir/$fileInTstToRunDir:$!\n" ;
print "File is : $fileInTstToRunDir\n" ;
next if($fileInTstToRunDir =~ m/^./ ) ;
while( ){
print $_ ;
if ($_ =~ m/ }
print RESULTS_LOG "File is : $fileInTstToRunDir\n" ;
#$count++ ;
# close FILE_2RUN ;
}
close RESULTS_LOG ;
close TST2RUN ;
