a tough question 4 u, problem in extracting tar & tar.gz files
when i am extracting tar.gz files with command tar xvzf, i am getting a message in every file, cannot change file ownership to uid uid no., cannot change file ownership to gid gidno., & one more thing is showing in that, file ownership of this tar file is 0755, when i am trying to change file ownership with chmod to 0777, it is not permiting me to do this. i think problem is with file permissions. this problem is not with a single package, a lot of package i am trying to extract, all having same problem. neither its a problem of linux vesion, bcaz 1st i am getting this problem in version 4, then i installed version 3, but same problem i get there also. plz tell me what to do.
