Hi guys,
I have a question. Since we can create 2 files ac, bc like these
$touch {a,b}c
can we do something similar
$ethtool -k eth{0,1} tx off or some similar command possible ?

it depends on how the command you're issuing handles its parameters. Actually, the braces {} just duplicate or triplicate a given parameter and then pass the expanded command line to the program being invoked. For example,
Code:
rm aa{p,sk,x}bb
would expand to
Code:
rm aapbb aaskbb aaxbb
That works because 'rm' is designed to deal with multiple file names in a single command. I'm not sure whether this works with ethtool. Reading the output of 'ethtool --help', I understand it the way that it takes only one interface name per call.
Agreed with the theory given by DOC CPU. it always depend on how command handles its parameters, commands those allow multiple parameters may work with this concept but others could give you a bad dream or day and may be more disastrous if used negligently.
