bash script - even more stupid question than last time.




tar -xf somefile.tar

if it is successfull returns 0
Code:
if [ tar -xf somefile.tar ]
    then
        echo fail
    else
        echo success
    fi
this makes sense to me! if it is successfull e.g 0 if will be false and echos success. Thing is, it doesn't complete tar -xf somefile.tar

How do I do this????

Thanks
