UNIX for Dummies Questions & Answers

Hello all,

I have a not so unix question for you guys(or maybe it is). I use PUTTY to login to serverA (my putty title shows as serverA.domainname.com)

Now from ServerA i do ssh user@ServerB (i have ssh public private key setup)...

now my question is when i do ssh and logon to serverB...my putty title still shows as serverA.domainname.com....is there anyway to "AUTOMATICALLY" change that to ServerB.domainname.com without going into putty menu and stuff ???

---------- Post updated at 12:15 PM ---------- Previous update was at 12:11 PM ----------

i know i can use something like below to change the title..but how can it be down automatically ?? without change profile and stuff on each server i do ssh to


printf "\033]0;asdf\007"

Put it into your profile files on the relevant servers, possibly into your PS1(prompt) variable. How to do so depends on the shells involved.

Thanks for the info...but i do not want to put in this all the server, we have well over 600+ servers...it would be painfull to do that....anyway to do this inside ServerA and when i ssh to serverB or serverC....it chanages automatically ?

Perhaps something like

Code:

ssh username@host export PS1="whatever" exec /bin/sh

Code:

$ ssh oracle@serverB export PS1="whatever" exec /bin/sh
ksh: /bin/sh: is not an identifier
$
$
$ which sh
/usr/bin/sh
$
$
$ ssh oracle@serverB export PS1="whatever" exec /usr/bin/sh
ksh: /usr/bin/sh: is not an identifier
$

You can replace ssh with your own function. So when you type ssh, you set title, execute real ssh, then set the title back. Try this in profile on ServerA:

Code:

ssh() {
        local args=( "$@" )

        #try find out destination
        while [[ $1 = -* ]]; do shift; done

        printf '\033]0;%s\007' "$1"
        command ssh "${args[@]}"
        printf '\033]0;%s\007' "$USER@$HOSTNAME"
}

i saved your funtion in a file and executed it that way...but complaints about this error...

Code:

$ ./test.sh
./test.sh: syntax error at line 2 : `(' unexpected
$
