i am not using any STTY command in that and i just dont want to modify .profile....i just want to know will it affect .profile or any other files if i will run it again and again..

[Laurent Menase · Accepted solution]

there are indeed the answer provided in the thread but you can also use -t option

$ ssh -t laurent@localhost ttytype
vt100
Connection to localhost closed.
$ ssh laurent@localhost ttytype
ttytype: couldn't open /dev/tty for reading
$

like that your ssh is executed on a tty which avoid all tty errors

[Laurent Menase]

just a remark, -t option uses a pty on the remote system, so it consume more ressource which can be limited, than without -t where the socket is use without a pty.

Now i used -t option with ttytype, thats true it is not showing the error but now it is not running the scripts on other 3 server... just it is showing the "vt100 Connection to 96.110.168.54 closed" and i am getting output from only server from where i am running it...

i am running this..
ssh -t host@ip ttytype "path/.ksh file"

[Laurent Menase]

add a set -x to your script to see what is executed and is not executed.

[vishal gangrade]

i checked it is not running the other 3 scripts..even some files which has to be created there are not creating..

[Earl_Crowder]

Remove "ttytype" from your command string. It was used to show the effect of the '-t' option.
