would like to view different between two commands 2

[peac3]

Hi guys,

I was trying to diff between 2 output commands "netstat -ar" and route?

At the moment I used 2 lines
netstat -ar > temp1 && route >temp2
then
diff temp1 temp2
rm temp1 temp2

Is there any one liner to produce this?

Those commands is only one of example and I have many things to compare basically.

Thanks in advance,

You can use something called "Process Substitution" which I find very useful... but unfortunately it's not available on many combinations of shells and/or operating systems.

$ diff <(netstat -r) <(route)

Otherwise, diff can also use stdin as a source by specifying - as one of the input filenames, so that would cut out at least one step:

netstat -rn > temp1
route | diff - temp1
rm temp1

Process subs is working..
Hopefully its working with other command as well..

Thanks Anni.
