I assume you wanted to post in the Requests part of the forum...

I don't know what OS you're working on, but on linux its not $ROWS but $LINES and not netstat.bin but just netstat and we don't redirect output to /dev/zero because that's an output device but to /dev/null because it accepts input

Anyways, I ran the script with these modifications and it worked like a charm. Here's the output of the script with set -x:

Hi Patsie,
I do not speak much English so I was confused when exposed here, sorryyyy.

my OS is debian squeeze/sid
ROWS to LINES : you're right
netstat.bin: my own script
/dev/zero: data sink for resize output

running your script

can you see that?? old_rows and old_columns are empty!!!
I don't know what happend
I think both script should be work

Apparently the environment vars $LINES and $COLUMNS are not available from your script. This could be because they are not set or because they are not exported. Either way, since you are already using the 'resize' command, I suggest using that to save and restore your settings:

I like what the man page shows

Don't work for me

I tested it on a linux live edition and does not work.
This is a bit weird because I did in c/c++ and all is well. Did not put the code here because it is a bash forum


Thanks for the answers.
