Please be aware that your entire pipe could probably be replaced by one single awk command.

Programming in ZSH, everything we use is based on FreeBSD.

This line gives me all my CPE in a list just fine.

Code:

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

This half is supposed to pull the version running for each CPE and display that next to the CPE name.

Code:

grep JUNOS $CPE_DEVICE/show.version | grep boot | awk '{print $5}'; done

I tried using -n with echo and it didn't help. I don't really know anything about this scripting stuff, so all of this is new to me.

After some research I was thinking that maybe a single awk command would work, but I'm not quite there yet in figuring it out.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
