Grep echo awk print all output on one line
Hello,

I've been trying to find the answer to this with Google and trying to browse the forums, but I haven't been able to come up with anything. If this has already been answered, please link me to the thread as I can't find it.

I've been asked to write a script that pulls a list of our CPE then have the script dig through the show.version file to pull a specific entry from there and display it all on one line.

This is the code I've come up with, but the display is all wrong. Note: I am no programmer/scripter, this is something new I'm learning for a recent promotion.

Code:
for CPE_DEVICE in `ls -d *cpe.domain.net`; do; echo $CPE_DEVICE; grep JUNOS $CPE_DEVICE/show.version | grep boot | awk '{print $5}'; done

My output comes out like this

Code:
device1-r0.cpe.domain.net/
[10.4R6.5]
device2-e0.cpe.domain.net/
device3-r0.cpe.domain.net/
[11.4R7.5]

I decided to dissect my code to see where the fault could be. I found that this half works fine in displaying the CPE devices on their own line each

Code:
for CPE_DEVICE in `ls -d *cpe.domain.net`; do; echo $CPE_DEVICE;

I'm not sure what I've done wrong in the second half of my code, but my output should look like this

Code:
device1-r0.cpe.domain.net/[10.4R6.5]
device2-e0.cpe.domain.net/[11.4R7.5]
device3-r0.cpe.domain.net/[11.4R7.5]

asadmin-stop-domain

asadmin-stop-domain(1AS)					   User Commands					  asadmin-stop-domain(1AS)

NAME

       asadmin-stop-domain, stop-domain - stops the given domain

SYNOPSIS

       stop-domain [--domaindir install_dir/domains][--terse=false] [--echo=false] [domain_name]

       stop-domain  stops the specified domain. If there is only one domain in the default domain directory (install_dir/domains), then no operand
       is required to stop the domain. However, if there is more than one domain, the domain operand must be specified. This command is  supported
       in local mode only.

OPTIONS

       --domaindir	       directory where the domain is to be stopped. If specified, path must be accessible in the filesystem. If not speci-
			       fied, the domainis stopped in the default install_dir/domains directory.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
			       formatted data for consumption by a script. Default is false.

       --echo		       setting to true will echo the command line statement on the standard output. Default is false.

OPERANDS

       domain_name	       name of the domain. Must be a unique name.

       Example 1: Using stop-domain

       asadmin> stop-domain sampleDomain
       Stoping Domain sampleDomain, please wait
       Domain sampleDomain stopped
       Command stop-domain executed successfully

       Where: the sampleDomain domain in the default domains directory is stopped.

EXIT STATUS

       0		       command executed successfully

       1		       error in executing the command
