Clear screen after every netstat update

skoda · 02-04-2015, 05:46 AM

Hi folks,

When i past this on the shell, the command rungs, but it does not clear previous data on each update.

Quote:

@echo off
:GoAgain
clear
netstat -atnp -w 5 | grep ESTA
goto GoAgain

what could be wrong?

Since this appears to be a windows batch file the correct syntax for clearing the screen is cls not clear.

Is this a shell script in linux?

Then goto command doesn't works.

So you have to put 'clear' command after netstat command.

Also for looping you would use the keywords 'while' or 'until'.

Then please explain your environment i.e is this just a command window etc.

Thanks folks,
this is centos 6.x shell.

ill take a look at while and until functions.

Agreed. I think I'm having a flashback to my DOS batch file days.
