Empty buffer when is full

Shell Programming and Scripting
1

Hello everyone!

This is the situation:

I execute this command from a bash script:

telnet 10.99.246.14 6001 >> output.txt

The question is:
How I do to execute this command and empty the buffer when is full?
The script is always running.

Thanks a lot!

What do you mean by buffer?

If by buffer you mean file, you could:

( telnet 10.99.246.14 6001 | split -a 4 -d -l 5000 - output. )

This will produce output.0000, output.0001, etc. split apart every 5000 lines. You can delete the old files and it will continue making new ones.

Actually, it can be far simpler. 'echo > output.txt' will clear it out.
