It goes into excludedata because that's where you tell it to go.
Imagine you're putting ssh host cat file into a script file, and running the script. [icode]./script.sh[/icode would print it to your terminal. ./script.sh > excludedata would go into excludedata.
The idea of redirecting the end of a while-loop is the same. We can capture the output of that whole section of code, just like it was a separate script file. It's one of the shell's handier features.
excludedata will contain the contents of each server's /usr/openv/netbackup/exclude_list, or "hostname fail" if it couldn't get through to it. logintest will contain the error output of ssh such as 'ssh: abhmq01.abh-sort.us.dhl.com: Temporary failure in name resolution' if anything couldn't be contacted. This way you can keep the data and error messages separate to make your output much easier to use later.
How would I pass awk output to a perl variable?
For example, I want to save the value in the 4th column into the variable called test. My best guess is something as follow, but I am sure this isn't correct.
$test = system("awk '/NUMBER/{print \$4}' $_"); (8 Replies)

ssh-argv0
SSH-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling
SYNOPSIS
hostname | user@hostname [-l login_name] [command]
hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is
equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally.
OPTIONS
See ssh(1).
FILES
See ssh(1).
