Removing banners from scp calls (AIX/KSH)
Hello all!
I am creating a script to synchronize key files on multiple servers in our environment. What I have works, but I am getting the banner for each of the servers in the output and it makes it difficult to quickly review when there are over a dozen servers in the array. I have tried a few different ways to suppress the banner (pipe this to grep for example) but nothing seems to work. Can someone offer a suggestion on how I could remove the banner text? Thanks in advance!

What I have today is:
Code:
 
SERVERNAME=`uname -n`
FILEDIR=/foo/bar
FILENAME=some.ini
for i in server2 server3 server5 server7 server8 server9 server10 
do
  if echo "$i" | grep -q "$SERVERNAME"
  then
    echo "Local machine, skipping..."
  else
    echo $i
    scp -p $FILEDIR/$FILENAME $i:$FILEDIR
  fi
done

The output looks like

What have you tried with grep?

You can use the -v option to exclude lines.

When I do the following line in the shell by hand it runs just fine, but shows the banner
Code:
scp -p /foo/bar/some.ini server2:/foo/bar

When I try
Code:
scp -p /foo/bar/some.ini server2:/foo/bar |grep some.ini

I only see the banner, not the result line I am actually interested in.
When I try
Code:
grep some.ini `scp -p /foo/bar/some.ini server2:/foo/bar`

it shows the banner, and then appears to wait for input (I have been escaping out).
When I try
Code:
scp -p /foo/bar/some.ini server2:/foo/bar |grep -v some.ini

I only see the banner, not the result line I am actually interested in (seems to be the same as without -v).

Could it be because this data isn't coming back through stdout? I found this for debian - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=134589

You can try putting a ".hushlogin" file in your home directory on the remote server(s).

Thanks for this suggestion, however I tried this earlier as well with no success. There must be a globl setting that overrides this...
