Need help with eliminating newlines with Perl
Good morning,

I need some help with getting rid of newlines with the output from a MYSQL query and putting the information into the right format that I need.

Here is the script as it is today:

#!/usr/bin/perl

my $uda = system("/opt/incontrol/mysql/bin/mysql -u root -ppassword --skip-column-names instancename -e \"select blah, blah from blahblah;\"");

chomp($uda);


This is the output:

+-----------------+-----------------------------+
| blockTechPhone | 312-555-1212 |
| blockTechName | This guy |
| blockAdminName | hat guy |
| blockAdminPhone | 312-555-3232 |
| blockTechEmail | me@you.com |
| block_name | this is a test|
| subnet_nets | off |
| blockSecName | gfsdg |
+-----------------+-----------------------------+

Note that the output is 10 lines long. I want to get rid of the first and the last line, since those are just clutter from the MYSQL output. Get rid of the "+-----------------+-----------------------------+" lines. I want the rest to be merged into one line like this:


-c uda,set -Tipv4_subnet -a 10.1.10.0 -o Personal -u username -p password --uda Subnet/blockTechPhone="312-555-1212" --uda Subnet/blockTechName="This guy" --uda Subnet/blockAdminName="hat guy" --uda Subnet/blockAdminPhone="312-555-3232" --uda Subnet/blockTechEmail="me@you.com" --uda Subnet/block_name="this is a test" --uda Subnet/subnet_nets="off" --uda Subnet/blockSecName="gfsdg"


What is the best way to get the output into one line I am trying and to insert the additional words that I want like I am describing. I appreciate any assistance!

I am fairly new to Perl, but have a lot of shell scripting experience. I am trying to do this in Perl.

uudemon

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
