Bug PERL Syntax Errors
Hi,

I am a newbie to PERL and working on a script. When running it I get a lot of compilation errors.

The actual command in the program (which is within a case structure) is given below

# This gives the actual count of inquires from a log file (It works fine when I type this on the command line)
# $output is the actual log file name

inq1) grep 'Number of inquiries :' $output | sort -u | awk '{print $5}' > inq1-CTR;


The following error message appears multiple times

Scalar found where operator expected at ./inquires_rpt line 104, near ""Number of inquires:" $output"
(Missing operator before $output?)
String found where operator expected at ./inquiries_rpt line 104, near "awk '{print $5}'"
(Do you need to predeclare awk?)

Please let me know what I need to do to fix this. I am also searching on the net for a solution.

Since I have no background in this, I don't have my debugging skills built up yet to scout for the hot spots.

Thanks

PERL-AFTER-UPGRADE(1)					User Contributed Perl Documentation				     PERL-AFTER-UPGRADE(1)

NAME

       perl-after-upgrade -- fixup FreeBSD packages that depend on perl

SYNOPSIS

	 perl-after-upgrade
	 perl-after-upgrade -f
	 perl-after-upgrade -v

DESCRIPTION

       The standard procedure after a perl port (either lang/perl5.6 or lang/perl5.8) upgrade is to basically reinstall all other packages that
       depend on perl.	This is always a painful exercise.  The perl-after-upgrade utility makes this process mostly unnecessary.

       The tool goes through the list of installed packages, looks for those that depend on perl, moves files around, modifies shebang lines in
       those scripts in which it is necessary to do so, tries its best to adjust dynamically linked binaries that link with libperl.so in the old
       path, and updates the package database.

       After installation of the new perl is complete, either by hand from the ports collection, or from a package, or via portupgrade, do the
       following:

       o go root;
       o run perl-after-upgrade utility.
	   Do not specify any arguments at first, so it does nothing destructive.  Pay attention to the produced output and especially to
	   errorlist at the end, if any;

       o run the utility again, with -f command line option.
	   This will actually do the work.  Again, pay attention to the output produced;

       o fix any reported errors;
       o reinstall required packages:
	   The utility will tell you what packages that depend on perl it could not handle.  It will also tell you why it happened (for example,
	   they were compiled against a binary incompatible perl).  If you want such packages to remain operational, you will have to reinstall
	   then by hand or via portupgrade.

       o review the files left in the older perl installation.
	   This is typically /usr/local/lib/perl5/site_perl/5.X.Y/.  There should be very little, if any, files in that directory and its subdi-
	   rectories, excepting a number of .ph files;

       o check that things work as they should;
       o remove backup files from the package database.
	   Those will be /var/db/pkg/*/+CONTENTS.bak;

       o that's all.
