hi to all.

for first i'm very sorry for my english..

when i'm using grep in this way to get the module path:

    cd $(sudo modprobe -v --show-depends r8168 | grep -Eoi "(\/[[:alnum:]\.\-]+){1,}" | grep -ivE "[a-z]{1}[0-9]+\.ko$")

...it return nothing

but if i switch '-v' to '-o' to test the command, it will print the right :

    $ sudo modprobe -v --show-depends r8168 | grep -Eoi "(\/[[:alnum:]\.\-]+){1,}" | grep -ioE "[a-z]{1}[0-9]+\.ko$"

    $ r8168.ko

so why the '-o' option check the regular exp, but the '-v' don't do his job??

Many Thanks
