(Newbie) Use of uninitialized value in concatenation (.) or string

J

Jesse Cary

I am making a script that issues commands, pulls certain text from the
results and puts that text into an HTML table. I got the first two
columns to display fine and used my method as a template to fill the
third column, but I get the error stated in the subject line.
Below is the code and the text I am pulling the date from;

#CODE#
# STORE THE NAMES OF ALL THE VOBS #
@VOBS = `cleartool lsvob -s | sort`;
if ( $#VOBS == -1 )
{
printf ("INFO: No MultiSited VOBs - exiting\n");
exit 0;
}
###################################
# GET THE SPACE INFO FOR EACH VOB # this part is working fine...
###################################
foreach $VOB_NAME (@VOBS)
{
chomp ($VOB_NAME);
$VOB_SPACE{$VOB_NAME} = `cleartool space \ $VOB_NAME`;

# EXTRACT ONLY THE SPACE USED IN MB FROM THE SPACE COMMAND #
if ( $VOB_SPACE{$VOB_NAME} =~ /(\d+?\.\d)\s+?\d+?%\s+?Subtotal/ )
{
$VOB_SPACE{$VOB_NAME} = $1;
}
# IF NO INFO AVAILABLE FOR A VOB PRINT "N/A" FOR NOT AVAILABLE #
else {
$VOB_SPACE{$VOB_NAME} = "N/A";
}
}
#########################################
# GET THE DESCRIPTION INFO FOR EACH VOB #
#########################################
foreach $VOB_NAME (@VOBS)
{
#chomp ($VOB_NAME);
$VOB_DSCR{$VOB_NAME} = `cleartool describe -l vob:$VOB_NAME`;

# EXTRACTING CREATION DATE #
if ( $VOB_DSCR{$VOB_NAME} =~ /created\s(\d\d-\w{3}-\d\d)/ )
{
$VOB_DATE{$VOB_NAME} = $1;
}
}

No you don't. The error you get from perl would include the file and
line number of the error. These are vital pieces of information.

If it's working fine, why are you showing it to us? Why take up space
with code not relevant to your problem? You should always post the
shortest complete program you can which demonstrates your issue.

foreach $VOB_NAME (@VOBS)
{
chomp ($VOB_NAME);
Click to expand...
printf("<tr><td>$VOB_NAME</td><td>$VOB_SPACE{$VOB_NAME}</td><td>$VOB_DAT
E{VOB_NAME}</td></tr>

Call it a hunch, but I'd bet your problem has something to do with using
$VOB_NAME twice and the string VOB_NAME another time.

You are missing

use strict;
use warnings;

Add those, clean up your code until you are strict and warning clean, and
chances are your problem will be gone.

If not then please repost your cleaned up and I'm sure someone will be able
to help you.
