yes you;re right, since the pfring package is not installed anymore, the $? == 1 and then the if statement takes the || clausole so I believe the pfring is already uninstalled. for the record, if you want to check if a pkg is present (or not) use something like this: pkg=pkg_name; rpm -qa | grep -q $pkg ; [ $? -eq 0 ] && echo $pkg is present || echo $pkg is not present or even simpler pkg=pkg_name; rpm --quiet -q $pkg ; [ $? -eq 0 ] && echo $pkg is present || echo $pkg is not present (this will work but you have to use the exact name of the package, so I usually prefer the former) I know this is a lot convolute, but it could be used in a script ;) ciao -v > > Regards, > Frwa. > > > On Mon, Aug 26, 2013 at 11:59 PM, [email protected] > <mailto:[email protected]> <[email protected] > <mailto:[email protected]>> wrote: > > On 08/26/2013 05:45 PM, frwa onto wrote: > > Dear Vpi, > > This command is not showing anything rpm -ev $(rpm -qa | > grep pfring) ? > > In case of success it wont produces any messages; if you want more > verbosity use something like this: > > rpm -evH $(.... > > -btw: you can test the bash exit status from the previous command, see [1] > > for example > > pkg=pfring; rpm -qa | grep -q $pkg ; [ $? -eq 0 ] && echo ok, $pkg > removed || echo $pkg not found, perhaps already removed? > > ciao > vito > > > [1] http://tldp.org/LDP/abs/html/exit-status.html > > > > > Regards, > > Frwa. > > > > > > On Mon, Aug 26, 2013 at 11:41 PM, [email protected] > <mailto:[email protected]> <mailto:[email protected] > <mailto:[email protected]>> <[email protected] > <mailto:[email protected]> <mailto:[email protected] > <mailto:[email protected]>>> wrote: > > > > Dear frwa, > > > > I think you've installed the pf_ring rpm without using yum, so just > type: > > > > rpm -ev $(rpm -qa | grep pfring) > > > > regards > > -v > > > > On 08/26/2013 05:32 PM, frwa onto wrote: > > > Dear All, > > > I have installed pf_ring using the yum method > previously.
