Shell Programming and Scripting

I'm using

Code:

fdisk -l > myFile

to get the file size of the device in a file where I want the output

but one line always go to the terminal and make my interface look ugly:

Disk /dev/sda doesn't contain a valid partition table

How do I stop this line from going to the command line with a device that does not have a valid partition table, because my program requires it to not have a valid one? Is fdisk calling another script?

Hi.

Perhaps the line to which you refer is output to standard error.

So, depending on what you want to do with it, you can:

a) get rid of it

Code:

fdisk -l > myFile 2>/dev/null

b) put it in myFile with the other output

Code:

fdisk -l > myFile 2>&1

Yes, that works. I read about standard error a few years back, and totally forgot about it. Thanks. Now my interface is b-e-a-u-tiful.
