@ typing creates new line

Dear Concern,

Please go through the article

As per the article, we need to initiate below commands. But after creating new session, we face same problem. Please advise.

stty intr "^c"
stty kill "^u"

Please find below out ~/.profile output

tabs@tabsdb02[TABS2]:/ccbs/users/tabs$ cat .profile
#
PATH=$PATH:/usr/local/bin:/ccbs/appl/tabs/bin
export PATH
. tabsenv

With Best Regards,
Md. Abdullah-Al Kauser

Those commands should show up in .profile , which they apparently don't unless they're in tabsenv .

Where do you define the terminal type??
If you are on an HP-UX somebody has messed up you .profile because that is not what it should look like... ( HP gives a good complete default .profile ...)

Dear,

The application vendor modified the .profile for that particular user in hp ux. What would be the location for 'tabsenv' file?

It should be somewhere on the PATH, or in your HOME directory, where .profile resides.

Maybe that user is like cron: not supposed to be in interactive mode then... Is it for a software?

Yes, .profile is the correct location for stty commands.
I suggest to put all stty settings in one line

stty erase "^h" intr "^c" kill "^u" susp "^z" eof "^d"
