Greetings Good people..!
I'm a beginner who just joined this community with lots of hopes. With much attempt I've written a script whcih does the following.
1. Will create a directory under “/x01/xx/xx/xx” by the current date, in the format of “YYYYMMDD” if it has not already been created. i.e: if the script is run on “01st of jan 2013”, the directory “20130101” will be created under the said path. So whenever there is a need to inspect the logs always look for a directory by the current date. i.e: if the script is run on “01st of jan 2013”, the directory “20130101” will be created under the said path. So whenever there is a need to inspect the logs always look for a directory by the current date.
2. Check if the log file(s) have already been downloaded earlier within the same day, and if not log(s) will be downloaded to the TODAY’s directory.
As you see on the subroutine "get_LOGS" I'm terminating the script if there are no files can be found on the server. Can someone go through the script and let me know what I should do to return a message saying that there are no files in the server? For an instance if I specify 2 or more files to be downloaded that are not really on the remote share, it would just complain about the first file and exit.(I know this is because of the die function, its just that I have no idea how to address such a scenario
Usage of the script: abc_logs.pl <file1> <file2>..file(n)
)use Net::SFTP::Foreign; use Cwd; my $LOGS_LOCAL_PATH = "/x02/ABC/abc/"; chomp $LOGS_LOCAL_PATH; my $LOGS_REM_PATH = "/x01/INT/ABC/vim/"; chomp $LOGS_REM_PATH; my $TODAY = `date +%Y%m%d`; chomp $TODAY; my @GETLOOP = @ARGV; unless ($#ARGV >= 0) { print "\nUsage: gtp_logs.pl <file1> <file2> <file3>.....<file(n)>\n\n +"; exit; } system("clear"); unless ( -d "$LOGS_LOCAL_PATH"."$TODAY") { print "Directory \"$TODAY\" doesn't exist. So creating the dir +ectory..!\n"; print "OK..Done.....!\n\n"; system("mkdir $LOGS_LOCAL_PATH/$TODAY"); } else { print "Directory already exists. Logs will be downloaded to == +> \"$LOGS_LOCAL_PATH$TODAY\".....!\n\n"; } # if_DOWNLOADED($LOGS_LOCAL_PATH,$TODAY,@GETLOOP); chdir("$LOGS_LOCAL_PATH"."$TODAY") || die "cannot cd to ($!)"; foreach my $GETL (@GETLOOP) { my $is_downloaded = if_DOWNLOADED($LOGS_LOCAL_PATH,$TODAY,$GETL); if(!$is_downloaded) { get_LOGS("172.25.70.221","abc","abc1234321","/x01/INT/abc/vim" +,$GETL); print "File \"$GETL\" downloaded to ==> \"$LOGS_LOCAL +_PATH$TODAY\"\n\n"; } else { print "File \"$GETL\" has already been Downloaded to ==> + \"$LOGS_LOCAL_PATH$TODAY\"\n\n"; } } sub get_LOGS { my $LOG_HOST = shift; my $REM_USER = shift; my $REM_PASSW = shift; my $REM_PATH = shift; my $REM_FILE = shift; print "Connecting to the sftp share! Please wait....!\n"; my $sftp = Net::SFTP::Foreign->new($LOG_HOST, user => $REM_USE +R, password => $REM_PASSW); $sftp->setcwd($REM_PATH) or die "unable to change cwd: " . $sf +tp->error; print "OK. On the share! Downloading the file \"$REM_FILE\"... +................!\n\n\n\n"; $sftp->error and die "Problem connecting to the share...!!!! " + . $sftp->error; $sftp->get($REM_FILE) or die "File does not seem to be present + on the remote share. Please re-request..!!!" . $sftp->error; return $REM_FILE; } sub if_DOWNLOADED { my $DWD_FILE_PATH = shift; my $DWD_DIR = shift; my $DWD_FILE = shift; if (-e "$DWD_FILE_PATH/$DWD_DIR/$DWD_FILE") { return 1; } else { return 0; }
PLease help out gentlemen. This will solve lots of other doubgts that I have when it comes to perl subroutines.
