print to a separate terminal screen

[rhnaeco]

hi, i have a very long BASH shell script which runs through quite quickly.
I want to see the results of part of the script as it is running- i have been doing this through nedit so far, but as i increase the number of input files i have so many nedits open i can't see the results anyway!!
i then tried 'more' but again it ran through so quickly ....

Is there a way of opening another terminal window in the bash script for any 'more' ? statements to be printed to that, whilst all the other echo's and working statements continue to print to the original?
or ANY way of viewing only these lines as they are created (short of removing the other comments)
thanks in advance

Hi

Maybe is not what you want, I don't really understand the question :
[ul]
[li]create a file : [tt][highlight white]touch /tmp/mydebug[/highlight][/tt][/li]
[li]start a [tt]tail[/tt] in some other console/terminal : [tt][highlight white]tail -f /tmp/mydebug[/highlight][/tt][/li]
[li]write debug messages to that file : [tt][highlight white]echo "Debug message" >> /tmp/mydebug[/highlight][/tt][/li]
[/ul]

yes, thats worked (using 'more' as the test is within another file). however- i am trying to write this script for others to use too, so i want the 'list of things to do' to be as short as possible- is it possible to open up a terminal and tail it from within the script, or is it going to have be set up before the script is run?

thanks

Hi

Open azn [tt]xterm[/tt] as background process :

touch /tmp/mydebug
xterm -e tail -f /tmp/mydebug &
echo now printing date >> /tmp/mydebug
date
echo now printing uname >> /tmp/mydebug
uname -a 
echo now printing uptime >> /tmp/mydebug
uname -a

xterm seemed to freeze on me when i tried this- but for the benefit of anyone else who uses fedora, i found this worked pretty well

gnome-terminal --command "bash -c 'tail -f filecheck.dat|less'"

thanks for your help again, scripting has become a much quicker task since i found this forum!!

Hi

Strange combination that [tt]tail[/tt] and [tt]less[/tt].
If this is what you want, Xdialog could be a better solution :

Xdialog --tailbox filecheck.dat 0 0

now you've said that, less isn't necessary. i got the code from someone who was having trouble keeping the terminal window open after running ls. I guess thinking about it, tail keeps it open anyway - duh! what can i say but i'm a beginner!
