Hello,

I have following problem. I have Centos 5.8 ( Final ) on Virtual Box.
I noticed very strange behavior of the terminals when resizing them.

My default shell is tcsh .

Let's assume that we have trial script try.csh with text in it:

#! /bin/tcsh -f

# Trial script

echo -n "Enter some value: "
set tmp = $<

if (${tmp} == "") then
echo "Only key [Enter] is typed"
else
echo "The entered value = ${tmp} "
endif

exit 0


If I execute the command ./try.csh
First following text appears: Enter some value:

If now I resize the terminal nothing happens, which should be the case.

But if I execute the command source ./try.csh
First same text appears: Enter some value:

And now if I again change the size of the terminal the text is changed to:
Enter some value: Only key [Enter] is typed

So it seems that sourced program considers resizing of the terminal like as [ Enter ] key is typed. In the company where I work we have RedHat5.3 servers and RedHat4.7 server, on the RH5.3 this problem is also existing, which is not the case for RH4.7 ones.

Please help me to solve this issue!

Best regards,

Hi, welcome to LQ!

I don't use either of the distro's you're mentioning, and I don't use tsch (bleagh ;}).

But I note that tcsh on Slackware64 13.37 shows the exact opposite of the behaviour you
describe (works when sourced, fails when run), and debian squeeze 64 behaves as expected
in both cases (resizing doesn't "answer" the prompt).

I can only assume that the difference lies in the way the terminal emulation in used is
set-up to respond to sizing events, and that it may differ between distros and versions
of distros.

Hello Tinkster,

It seems that the issue is not caused from the terminal emulator itself.
Because in Centos5.8 I have this issue using Terminal, konsole and xterm.
In RedHat5.3 I have the issue using konsole, xterm and gnome-terminal.

Best regards,
