Hi there all, sorry for the dumb newbie question: I have created a directory in my /usr directory called 'scilab'. I would like to have read/write permission for that directory and for directories within. glenn(a)glenn-acer:/usr$ ls -al total 168 drwxr-xr-x 13 root root 4096 2009-01-06 22:35 . drwxr-xr-x 21 root root 4096 2008-12-19 16:14 .. drwxr-xr-x 2 root root 36864 2009-01-03 00:27 bin drwxr-xr-x 2 root root 4096 2008-12-19 16:09 games drwxr-xr-x 36 root root 4096 2008-12-22 01:03 include drwxr-xr-x 167 root root 69632 2009-01-03 00:27 lib drwxr-xr-x 2 root root 4096 2008-12-22 21:34 lib32 lrwxrwxrwx 1 root root 3 2008-12-17 23:37 lib64 -> lib drwxr-xr-x 10 root root 4096 2008-07-02 21:47 local drwxr-xr-x 2 root root 12288 2008-12-27 23:46 sbin drwxr-xr-x 2 root root 4096 2009-01-06 22:39 scilab <----------- drwxr-xr-x 317 root root 12288 2009-01-03 00:27 share drwxrwsr-x 6 root src 4096 2008-12-19 16:10 src drwxr-xr-x 4 root root 4096 2008-12-20 13:10 X11R6 glenn(a)glenn-acer:/usr$ Would I be right to assume that I needed the ownership of scilab to be glenn instead of root, i.e: drwxr-xr-x 2 glenn glenn 4096 2009-01-06 22:39 scilab how do I command Linux to change from root to me?
