Terminal scrolling display

Yaroki — Wed, 12 Dec 2012 07:37:33 GMT

Hello,

I'm running HP-UX c8000, B.11.11

The terminal type is dtterm (echo $TERM).

The problem is that the terminal does not show the entire "history" when I scroll the window backwards.

If I run ls -l and the output runs to terminal I can't see the whole output.

How can I fix it?

BR,

Yali

I think there are options to dtterm to set the number of lines of "scroll back" on the terminal. That is what you need to investigate.

To set the number of linkes of scroll back for dtterm, you use the '-sl' option.

For example:

dtterm -sl 4000l

will invoke dtterm and give you 4000 lines of scroll back capability. The maximum number for scroll back is 32,767 (I think).

You can also add -sb to get a scrollbar.

Thank you for the replies.

The command dtterm -sl 4000l is good only for the next opened terminal.

How do I make this setting to take place persistently for root and for other users?

Why does this terminal setting is different for my other machines? Is it part of the env variables?

Users that are using X, need to know how to configure their own display. Or they are better off using Windows to do this.

>Why does this terminal setting is different for my other machines?

Mine was coded in menus. Or in ~/.Xdefaults.

Hello,

Is there a file to define the "dtterm -sl 4000l" command ?

We're asking you. How do users invoke dtterm? From the shell? Or from dtterm menu?

Sorry, I missed that.

Users are invoking terminals from the Front Panel menu.

I add the .Xdefaults file into the home directory of a user and add the following:

xterm*scrollLine: 1000

Then I ran:

xrdb .Xdefaults

but still, I can't see enough scrolled lines when I scroll back.

In my old .mwmrc there was an explicit call to hpterm where I could set it.

>I add the .Xdefaults file into the home directory of a user and add the following:

Don't you need dtterm?

>xrdb .Xdefaults

I thought I used to use -merge?

>I can't see enough scrolled lines when I scroll back.

Do you also need to enable the scrollbar?

I can see the definition for that in .mwmrc file.

> Don't you need dtterm?

does not work as well

> I thought I used to use -merge?

did you mean to invoke "xrdb .Xdefaults -merge" ?

>Do you also need to enable the scrollbar?

I do have the scrollbar but when I scollback I can't see the first command I ran before on that terminal.

>does not work as well

dtterm(1) has: saveLines

>did you mean to invoke "xrdb .Xdefaults -merge"?

Almost: xrdb -merge .Xdefaults

Many thanks!!!!

It is finally works. The saveLine parameter was added to the .Xdefaults file as follow:

dtterm*saveLines:1000l

then

xrdb -merge .Xdefaults

and the new terminal takes the effect.

Hello,

I Installed a new B.11.11 OS and I face the same problem again.

I tried to edit .Xdefaults with the relevant lines but somehow it doesn't work this time.

I attached the screen shut

This is the end of the file with my 3 additional lines at the end.

The lines:

dtterm*scrollLine: 10000
dtterm*scrollBar: true
dtterm*saveLine: 1000l

should have Lines rather than Line:

dtterm*scrollLines: 10000
dtterm*scrollBar: true
dtterm*saveLines: 1000l

Ok,

It is fine now. (there was a bad value name inide). So for dtterm sessions it works!

Also, we are running scripts that thier outputs do into files.

These files display "online" on the screen and the person how runs it should check the running of the program.

But now due to the scrolling problem it is impossiable to view whole the "running".

Please advice,
