Hi listers. I have encountered the problem of let's say you are looking at usage for a particular program. And it scrolls to the next screen. Is there a way to be able to look at the previous screen? Like does the screen or the operating system keep a temporary buffer of the previous screen until refreshed by another shell command? What I'm refering to is something similar to a scroll back buffer that I believe used to exist in Dos. Does such a thing exist under Linux? I thought I read in some howto that the keystroke for this was alt+backspace or something? Thanks!

Shift-pageup and shift-pagedown activate the scrollback
feature in Linux but it doesn.t work with speakup
to my knowledge.
I use screen for this with the control-leftbracket keystroke and scroll back that way.
To make a command show usage and page the result do this:
ls --help 2>&1|less
the 2>&1 redirects standard error to standard output so you can page the result
through a pager.
regards, Kerry.

Hmm, have never needed the 2>&1, don't know what I'll be missing then.

Cheers.

Hi Toby. Thanks for the info. Is there more info as to why you use >2&1|? Why not something like redr=stdout|less?

Some programs send their help text to standard error, rather than standard
output. I personally think that people who do this should have their head
read. At any rate, the 2>&1 is needed for these programs to send standard
error to standard output.

Some programs like dd often run in a pipe.
It can be argued that if incorrect command-lines are given, the error
should indeed go to standard error. My feeling is that errors
should go to standard error and --help should go to standard output
since the --help option is exclusive. This is how most GNU tools behave but
it can not be relied upon.
Many programmers argue that help text for a filter should go to standard error
to prevent usage information being inadvertantly written to a pipe.
Perhapse they need their head read but there is method in the madness.
Regards, Kerry.

Hi Kerry. Do you mean a utility such as less?

When this happens, I try piping the output through less, which doesn't work in allll cases.

* Scroll Back?

Is there any way one can scroll back the screen while in a regular
console with speakup enabled? I thought someone had suggested the
shift page-up key but trying that did me nothing; nor did any other
combination of page-up keys and other control keys. I am refering to
the page-up key on the six pack of keys.
Any ideas?
